The Unknown Dangers of Nanotech
Infinitely small nanostructures will soon permeate your food, body and environment on the grounds of improving structure, preventing disease and enhancing traits, but their potential to be toxic, invade immune systems or simply behave erratically and unexpectedly could pose real dangers in a burgeoning industry rapidly delving into the unknown

Aaron Dykes / Jones Report | December 6, 2007

Nanotechnology could become a revolutionary force in the near future, but its microparticulate nature poses uncertain risks and unknown dangers as it infuses unchecked with foods, cosmetics, medical treatments, plastics and many other materials which already permeate hundreds of consumer products.

Many scientists have recently aired their concerns in an apparent paradox-- the very developments expected to work wonders across the gamut of science, medicine, technology and everyday life could expose consumers to the vulnerability of nanotech's infinitely small size and potential instability.

The Economist reports that:

"Nanoparticulate versions of a [known] material can act in novel ways... despite hundreds of years of experience in chemistry, it is not easy to predict how a substance will behave when it is made extremely small. Plenty of research suggests that nanoparticles of harmless substances can become exceptionally dangerous. Materials, such as gold, that would not react to other substances become reactive. [Yet] silver can have antimicrobial properties."

Despite an insufficient understanding of the adverse effects nanoproducts could have on health and the environment, big money is pouring into an industry expected to grow to $1 trillion by 2010 and several trillion by 2014, which governments across the globe are already stimulating with cash injections and heavy subsidies.

Channel News Asia expects that nanotech will "permeate almost every aspect of our lives" in the "time to come."

The Economist: The risk in nanotechnology - A little risky business

Nanotechnology a 'bigger concern' than GM foods

Nanotech, genetic modification, and gene splicing are not of our Creators design, so there is no doubt that they are a demonic tool used for the control of mankind by the PTB. How else are they going to get rid of 80% of the worlds population. I personally believe that we already have the cure to every disease in earths resources, be they plants, animals or minerals. The key is unlocking the code of how to use them! There probably is no cure for the manmade plagues the PTB want to eventually release, or have released on mankind. I hope we have the time to delay or avert the madness of the NWO. If its going to happen, it will have to start in the USA. We still have enough freedom to turn the tide. We REALLY need a Ron Paul Revolution! ;) ;) ;)

You left out "all of the above" out of the poll.  That's what I see as the most correct answer.

Apart from a book called 'Prey' by Michael Crichton and the fictional Star Trek universe and I've never really read much nanotechnology.  But after reading the articles in this post it seemed imperative that I learn more.

It seems that nanotechnology has been around for about 20 years and can be found today in a myriad of products such as skin creams, toothpastes, sporting goods, jewelry and even some clothing.  But what is most alarming is how few experiments have been conducted on the effects this may have on the environment, living organisms and us as a species.

Recently, expiremen ts have revealed that high concentrations of nanotubes could damage the lungs of rats and mice and can be absorbed in the livers of research animals. Additionally tests have shown that within 48 hours of being exposed to a very low concentration of nanoparticles, fish produced brain damage that resembles Alzheimer's disease.  Another cause for concern is that if they can be absorbed by cells, then theoretically it is possible that they can enter the food chain through bacteria and pose a serious health threat to all living creatures not just those that come into direct contact with them.

A June 2004 report from the European Union sponsored Nanoforum notes that "some scientists have already compared nanotubes with asbestos in terms of risks and danger. John Howard, head of the US government's safety research body NIOSH told a May 2004 conference "Very little is known currently about how dangerous nanomaterials are, or how we should protect workers in related industries".  He also added that nano products in development "are so far from our current understanding that we can not easily apply existing paradigms to protecting workers?!"

So along with nuclear power, gene splicing and GM crops we now have nanotechnology to contend with.  Alike many scientific breakthroughs in the past 100 years, humanity wrapped up in their own ego and greed are ignoring the potential destructive consequences of their discoveries.  In doing so we are now on a knife edge which threatens our very existence and for this reason I doubt the elite will get their chance to use nanotechnology to create their desired brave new world.  Maybe they are beginning to realise this too and I wonder whether this is the real reason for the creation of the huge 'Doomsday Seed Vault.'  :o

A video game released in 2000 called Deus Ex addresses some of perils posed by nanotech.
Deus Ex takes place in a dystopian future in a world that draws heavily upon present day conspiracy theories. This dark setting is enhanced by the fact that the entire game takes place at night, a backdrop which adds to the atmosphere of conspiracies and stealth. The game contradicts itself in several instances regarding the exact year in which the events of the story take place, but information in the sequel Deus Ex: Invisible War reconciles this inconsistency via retroactive continuity, placing the events of Deus Ex in the year 2052.[24] Most of the game takes place in fictionalized versions of real-world locations, including New York City, Hong Kong, Paris, Area 51, and Vandenberg Air Force Base.

The plot of Deus Ex depicts a society on a slow spiral into chaos. A lethal pandemic known as the "Gray Death" ravages the world's population, especially within the United States, and has no cure. A synthetic vaccine, "Ambrosia", manufactured by the company VersaLife, nullifies the effects of the virus, but is in critically short supply. Because of its scarcity, Ambrosia is available only to those deemed "vital to the social order", and finds its way primarily to government officials, military personnel, the rich and influential, scientists and the intellectual elite. With no hope for the common people of the world, riots occur worldwide, and a number of terrorist organizations have formed with the professed intent of assisting the downtrodden, among them the National Secessionist Force of the US and a French group known as Silhouette.

In order to combat these threats to the world order, the United Nations has greatly expanded its governmental influence around the globe. The United Nations Anti-Terrorist Coalition is formed, with the intent of maintaining peace internationally and combating the world's ever-growing number of terrorist groups.[25] It is headquartered near New York City in a bunker beneath Liberty Island, placed there after a terrorist strike on the Statue of Liberty.[26]

Synopsis:  ...With the feud resolved, JC is allowed to meet with Tong who deactivates his killswitch. While infiltrating the Versalife building for Tong, JC discovers that VersaLife is manufacturing the Gray Death, which is caused by a nanovirus.[28] JC retrieves plans for the virus, and destroys the universal constructor used to produce it.

Analysis of the virus reveals that it was developed in-part by the Illuminati...."

Oh I love Deus Ex Invisible War, havn't played it in years, I'm gonna dig it out.
In the meantime, czech it out: it's too late to worry about nanotech, they're in us already
This is one of those stories that you friends just point blank will not believe. Most people have no idea that technology they consider to be decades off is alive and well in JASON and so on...

104 products on shelves already contain toxic 'grey goo' by stealth, say Friends of the Earth
Potentially toxic chemicals are being incorporated into food, packaging, health supplements and other products by stealth, it is claimed.

Manufacturers boast that nanoparticles can deliver drugs or vitamins more effectively, kill harmful bugs in food or create self-cleaning windows.

But scientists, consumer groups and green campaigners fear the technology is being introduced into the diet, body and environment without proper safety checks.

Nanoparticles are 80,000 times thinner than a human hair - so small they can cross membranes protecting the brain or a baby in the womb.

Critics say it is not known how such tiny particles will interact with the body and organs in the long term, whether they are toxic or how long they will persist in the body.

Doom-mongers have warned that nanoparticles could mutate and reproduce out of control, consuming all life on earth, a scenario often referred to as "grey goo".

Yesterday a report by Friends of the Earth said current regulations are "ill-equipped" to deal with the unique properties of nanoparticles.

It said: "Despite concerns about the toxicity risks of nanomaterials, consumers are unknowingly ingesting them because regulators are struggling to keep pace with their rapidly expanding use."

The study found at least 104 food and agricultural products available in Europe, including the UK, which use nanotech particles or technology.

This includes some nutritional supplements under the Solgar brand, cling wrap and containers, antibacterial kitchenware, processed meats, chocolate drinks, baby food and chemicals used in agriculture.

Safety fears over nanocosmetics
Wednesday, 5 November 2008

Cosmetics containing tiny "nano" particles are being used widely despite unresolved issues surrounding their safety, a consumer watchdog warns. Many skin care products, including sunscreens and wrinkle creams, contain this technology to make them easier to apply and invisible on the skin.

But experts are concerned about their possible long-term effects on the body, Which? reports. Which? wants more safety checks and tighter regulation of their use.

It says, at the moment, consumers cannot tell which products use nanomaterials as many fail to mention it.


Nanotechnology is the science of manipulating atoms and molecules on the nanoscale - 80,000 times smaller than the width of a human hair. The cosmetics industry is using it to create new materials with novel properties.

On the flip-side, that might mean unexpected risks.

Which? wrote to 67 cosmetics companies, including all of the main brands as well as smaller ones, asking them about their use of nanotechnology, what benefits they thought it brought and how they ensured product safety.

Seventeen firms responded, and of these, eight were willing to provide information about how they used nanotechnology. Most of the eight, which included The Body Shop, Boots, Nivea, Avon, L'Oréal, Unilever, Korres and The Green People, used nanotechnology for the UV filters in their sunscreens.

Which? also found evidence of other cosmetics companies offering nanocosmetics online.

Skin penetration

These products included nano emulsions - preparations containing oil and water droplets reduced to nano size - used to preserve active ingredients, such as vitamins and anti-oxidants, and for their lightness and transparency.

Another example was a type of nanomaterial called "fullerenes" used in anti-aging cream products.

Scientists have raised particular concerns about potential toxicity of fullerenes if they were able to penetrate the skin. There is also a concern that the nanomaterials in sunscreens might be able to breach sunburned skin.

The Which? report says all nanocosmetic products should have an independent safety assessment. The precautionary principle should be applied to products where there are potential risks but where it is not currently possible to assess their safety so that consumers are not put at risk, it says.

Sue Davies of Which? said: "We're not saying the use of nanotechnology in cosmetics is a bad thing, far from it. Many of its applications could lead to exciting and revolutionary developments in a wide range of products, but until all the necessary safety tests are carried out, the simple fact is we just don't know enough.

"The government must introduce a compulsory reporting scheme for manufactured nanomaterials so we are all aware - and only those that are independently assessed as safe should be allowed to be used in cosmetics."


In September 2006, the government launched a voluntary reporting scheme for all engineered nanomaterials to find out what was, or could be, on the market, to guide the development of regulations. This has had a limited response - 12 responses in two years - and is now under review.

A spokeswoman for the Cosmetic, Toiletry and Perfumery Association said: "The industry is working with government to provide more information on the safety of these products.

"The safety assessment of cosmetic products is a legal requirement and that assessment is robust and takes into consideration the particle size of ingredients."

Professor Dame Ann Dowling, chairman of the Royal Society working group on nanotechnologies, said: "The Royal Society has been calling, for the last four years, for companies to make public the safety testing methods they have been using on their nanoproducts. We are disappointed at continuing lack of transparency in this area.

"More research does need to be done on the effects of manufactured nanoparticles on human health and the environment. This is important so that regulation can be built on a proper understanding of any risks."

A European Commission spokeswoman said: "We are working towards improving our ability to assess the safety of all consumer products using nanomaterials including cosmetics.

"The Scientific Committee on Emerging and Newly Identifed Health Risks (SCENIHR) is currently preparing an update of its 2006 opinion on the risk assessment of products of nanotechnologies. This update will be available in January 2009."

Boots said it did not consider its current use of materials was of concern to health.

The Body Shop said its products helped to protect human skin.

Nano-treatment to torpedo cancer
Tuesday, 10 March 2009
Full article:-

Nanotechnology has been used for the first time to destroy cancer cells with a highly targeted package of "tumour busting" genes.

The technique, which leaves healthy cells unaffected, could potentially offer hope to people with hard-to-treat cancers where surgery is not possible. Although it has only been tested in mice so far, the researchers hope for human trials in two years.

The UK study is published online by the journal Cancer Research.

The genes were wrapped up in microscopic nano-particles, 80,000 times smaller than the width of a human hair, which were taken up by cancer cells, but not their healthy neighbours. Once inside, the genes stimulated production of a protein which destroys the cancer.

The researchers say the technology could potentially be particularly relevant for people with cancers that are inoperable because they are close to vital organs. They hope it will eventually also be used to treat cancer that has spread.

Lead researcher Dr Andreas Schatzlein, from the School of Pharmacy in London, said: "Gene therapy has a great potential to create safe and effective cancer treatments but getting the genes into cancer cells remains one of the big challenges in this area.

"This is the first time that nanoparticles have been shown to target tumours in such a selective way, and this is an exciting step forward in the field.

"Once inside the cell, the gene enclosed in the particle recognises the cancerous environment and switches on. The result is toxic, but only to the offending cells, leaving healthy tissue unaffected.

"We hope this therapy will be used to treat cancer patients in clinical trials in a couple of years."

China's giant step into nanotech
Thursday 26 March 2009
Full article:-

Nanotechnology - the manipulation of matter on an atomic scale to develop new materials - is an industry predicted to be worth nearly £1.5tn pounds by 2012, and China is determined to corner the biggest chunk of the market.

Its investment has already surpassed that of any other country after the US. Since 1999, China's spending on research and development (R&D) has gone up by more than 20% each year. A further boost will come from the £400bn economic stimulus package announced by the Chinese government this year, £12bn of which has been ringfenced for R&D.

Tiny superpower

"The overall trends are irrefutable," says Dr James Wilsdon, director of the Science Policy Centre at the Royal Society, and author of the Demos report "China: The Next Science Superpower?". "China is snapping at the heels of the most developed nations, in terms of research and investment, in terms of active scientists in the field, in terms of publications and in terms of patents."

China now produces more papers on nanotech than any other nation. Nanotech plants have sprung up in cities from Beijing in the north to Shenzhen in the south, working on products including exhaust-absorbing tarmac and carbon nanotube-coated clothes that can monitor health. Last month, researchers from Nanjing University and colleagues from New York University unveiled a two-armed nanorobot that can alter genetic code. It enables the creation of new DNA structures, and could be turned into a factory for assembling the building blocks of new materials.

"There's no end of areas in which nanotech is already being used," says Wilsdon. "It's the product of targeted investment for the development and refinement of novel nanomaterials. And the reason the Chinese focus on that area is because it's closer to the market."

Small-scale war

China, like the US, is also assumed to be focusing much of its R&D investment on military applications. "There's a lot of concern about the use of nanotech with weapons," says Wilsdon. "I'm sure China is spending significant amounts of their R&D budget on military uses."

Tim Harper, founder of the nanotech consultancy Cientifica Ltd, says carbon nanotube composites could be used to strengthen armour, that non-scratch nano-coatings are being developed for cockpits and researchers are trying to find a nano replacement for military-use batteries. "The US is working on all of these things, so I'm sure the Chinese are doing much the same," he says.

Underlying these developments are serious safety concerns. Nanoparticles are so small they are easily inhaled and absorbed through the skin. Dr Andrew Maynard, the chief science advisor to the Project on Emerging Nanotechnologies at the Woodrow Wilson International Center for Scholars in Washington, says that some nanoparticles could be deadly. "Nothing has yet been confirmed, but there are strong suggestions that inhaling these particles could cause lung cancer or lung disease," he says. "If carbon nanotubes behave anything like asbestos, we won't know what the health impacts are for about 20 years, because that's how long it can take from exposure to the onset of the disease."

Most experts agree that a system of stringent safety regulations and comprehensive quality inspection checks is needed before China's nano-coatings, cosmetics and clothes are stocked by supermarkets. "The economic crisis could prove the catalyst that Chinese nanotech companies need to get this system in place," says Harper.

Under the microscope

The global nanotechnology market could top $2tn by 2012, predicts Tim Harper, founder of the nanotech consultancy CMP Cientifica. "What we see is a big take-off in 2011, and by 2012 the industry is really going to be booming," he says. "We've been pumping hundreds of millions of dollars into the nanotech industry for the last decade and we're finally getting to the point where we're seeing products being manufactured and sold."

Harper predicts that by 2010, areas of nanotechnology and biology will have merged, setting in motion the production of a wealth of new drugs and clinical equipment (such as the vials of nanomaterials for use in health products, clothes and cosmetics). His research sees nanotech pharmaceutical and healthcare products worth an estimated $3.2tn by 2012, with military-use nanotech products taking 14% of the total market and worth $40bn.

Richard Appelbaum, from the Center for Nanotechnology in Society at the University of California, puts the global nanotech market figure at $2.6tn by 2014, or 15% of manufacturing output in that year. China, along with 40 other countries including the US, UK and Japan, is investing in nanotechnology "as a major key to global economic competitiveness", he says.

If any one nation succeeds in cornering the giant's share of the market, it "would be sufficient to confer global economic leadership on the country", he adds.

Nanoparticle lung threat blocked
Thursday, 11 June 2009
Full article:-

Scientists have identified how a type of tiny nanoparticle can cause lung cancer - and blocked the process.

The fledgling science of nanotechnology promises huge advances in science and medicine, but there are concerns about its safety. In particular, the microscopic particles it employs have been shown to have toxic effects on the lungs.

The research, by the Chinese Academy of Medical Sciences, appears in the Journal of Molecular Cell Biology. However, experts said it was not possible to draw general conclusions about all nanoparticles from a study focusing on one specific type.

Nanotechnology involves the modification of atoms and molecules to create new materials which may have unusual physical, chemical, and biological properties. In medicine alone it is hoped it could be used to develop more effective and better targeted drugs, and new ways to detect and treat disease.

The market is potentially huge, but safety concerns threaten to hold progress back.

Research has shown that most nanoparticles migrate to the lungs, but there is also concern about potential damage to other organs.

The latest research focused on a class of nanoparticles being widely developed in medicine - polyamidoamine dendrimers (PAMAMs). In tests on cells in the lab, the researchers found the particles cause lung damage by triggering a type of programmed cell death known as autophagic cell death.

Autophagy plays a normal part in cell growth and renewal, but over-activity can lead to unwanted cell death. However, the researchers also found autophagy could be blocked by using a drug inhibitor.

The findings were confirmed in tests on mice. Animals exposed to PAMAMs showed higher levels of lung inflammation, and higher death rates. But those that were first injected with the inhibitor were less badly affected.

Lead researcher Dr Chengyu Jiang said: "This provides us with a promising lead for developing strategies to prevent lung damage caused by nanoparticles.

"Nanomedicine holds extraordinary promise, particularly for diseases such as cancer and viral infections.

"But safety concerns have recently attracted great attention and with the technology evolving rapidly, we need to start finding ways now to protect workers and consumers from any toxic effects that might come with it."
