Here is a terrific article about how Nanotechnology works from the guys at 'How Stuff Works': In order to understand this newly emerging world of nanotechnology, we need to get an idea of the units of measure involved, as well as some of its most redeeming properties.
Indeed, size matters!
A nanometer is one-billionth of a meter. This is smaller than the wavelength of visible light but one hundred-thousandth the width of a single human hair.
Couple this incredibly small scale size with strength and durability and nano-particles/nano-materials are one of the fast growing industries around the globe.
Nanotechnology is often used for the delivery of a 'payload' in medicines, foods, micro electronics, DNA mapping, pesticides. It can also be used in and just about any other chemical, bacterium, organic or inorganic material. It would seem imperative to have manufacturing safety regulations in place in light of such widespread use.
Unfortunately, nanoparticles nor the products and materials that contain them are subject to any special handling or labeling.
A branch called Nanotoxicology deals with these issues.
Some types of particles, the smaller they are, the greater their surface area to volume ratio and the higher their chemical reactivity.
Greater chemical reactivity of nanomaterials can result in free radicals.
ROS production has been found in a diverse range of nanomaterials including carbon fullerenes and carbon nanotubes. ROS and free radical production is one of the primary mechanisms of nanoparticle toxicity.
What does this mean in summary?
When something causes ROS production inside our cell tissues, it can easily lead to cell mutation and even cellular death.
Due to the nano-size of these particles we have to be careful with the ones we can ingest or inhale or ones that have contact with our skin.
Here are some Nanotech materials which are already in our daily lives:
Skin care products
Cosmetics
imaging and scanning diagnostics like MRI devices
Cancer detection
artificial Sunscreens
Vitamins and supplements
intravenous medicines, both prescriptive and over the counter
Building materials, sealants
food packaging
I have a copy of a clinical impression toxicological report that shows my family's exposure to many of the already existing nanoparticles; nano-anchors, nano-spheres, nano-claws, and smart dust. I have added these to my book which you can get at http://www.healinggrapevine.com
Smart Dust may very well be the champion of all these nano-particles.
Whatdoes that mean for our future generation's safety?
I have to admit it is sounding a bit like the Star Trek. Being assimilated by the Borg.
