Other nanorobots might be programmed to single out and kill cancer cells without damaging surrounding healthy tissue.
Nanoscale zinc oxide particles absorb UV radiation in sunscreen lotions, and nanoscale “whisker-like” particles are used to coat the surface fibers of fabric to create a stain-repelling surface.
Bayoxide® E 33 is so effective at removing arsenic from groundwater that a contact time of three to five minutes can reduce an arsenic concentration of 10 to 50 µg/liter to below five µg/liter. Today Bayoxide® E 33 is used in municipal system sin Chile, Europe, India, Japan, the United States and other global markets.
(The Environmental Protection Agency has mandated that a liter of drinking water may not contain more than 10 µg of arsenic.) Use of the technology began in England in 2002 and moved into the U. Two very successful nano-based products that have been in the marketplace for several years are PPG’s Cerami Clear.
However, this is a very small area of what's currently called nanotechnology, a term that has been broadened over time by researchers working on a wide range of small stuff.
It should be noted that a lot of nanotechnology is not molecular.
Nanotechnology provides the foundation to build chips, one atom at a time, to create devices much smaller than those that can be manufactured using traditional semi-conductor processing methods.Sun Clean self-cleaning glass is made using an ultra-thin layer, several nanometers thick, of a light-sensitive coating of titanium dioxide which is fused directly into the glass while it is still molten, thereby making it an integral part of the outer glass surface.The result is a glass product with an ultra-thin layer of metal that does not cut down on the light passing through the window, but does chemically react with the ultraviolet rays in sunlight to oxidize organic material on the glass surface.So-called nanorobots might serve as programmable antibodies.As disease-causing bacteria and viruses mutate in their endless attempts to thwart medical treatment, some scientists envision nanorobots that could be reprogrammed to selectively seek out and destroy them.Many types of nanoparticles, for example, are only approximately similar within a sample, yet not identical to each other as molecules are.In response to nanotechnology’s expansion, Drexler developed the terms molecular nanotechnology, molecular manufacturing, and productive nanosystems to refer more succinctly to his work.Many of the significant applications of nanotechnology are expected to drive ever-more-powerful computers and communication devices.This will be essential if we are to continue the revolution in computer hardware beyond the next decade.Cerami Clear uses nanoparticles embedded in the clear coat layer of an automotive paint system to provide increased resistance to scratches, car washes and hard to remove tree sap.The product is the standard automotive finish on Mercedes Benz cars.
