In the scope of defining nanotechnology, it
is better and easier to understand it by breaking it down into different
definitions. In addition to incremental nanotechnology, evolutionary nanotechnology
is a phrase coined by scientists to describe how we move beyond more simple
products and move toward products that have been changed and improved on a
nano-scale level. Devices that utilize this technology can be responsible for
sensing the environment, converting energy from one form and source to another
and the ability to process information.
These kinds of devices can include many nano-scale
sensors that show the large surface area of nanotubes made up of carbon and
other kinds of nano materials in order to detect contaminations or biochemicals
in our environment. Some other products that are derived from evolutionary
nanotechnology are kinds of semiconductors that can be used as quantum dots and
wells that scientists are using to create better quality types of lasers.
Scientists and researchers are working to
develop more sophisticated methods of encapsulating certain molecules and then
being able to deliver them as needed and on demand to the targeted drug
destinations. When combined, incremental along with evolutionary nanotechnology
have become the driving forces behind the current buzz of excitement in the
educational and scientific communities. There are currently big steps being
taken in evolutionary nanotechnology, and more and more types of products
should be coming available on the market to the public over the course of the
next few years.
Although evolutionary nanotechnology has
been around for a while, it is a constant work in progress for scientists and
researchers to be able to fine tune and develop products that they will be able
to market in the healthcare and other industries.
So where does this leave the original
skeptic views of radical nanotechnology? According to Eric Drexler back in
1986, an influential book was published that created visions of sophisticated
nano-scale kinds of machines that could operate with precision on an atomic
scale. This view came to be known as radical nanotechnology and included the
notions of being able to use materials like diamonds to make nano-scale
structures by the movement of reactive molecular particles into place. This
early view was extremely mechanical in approach and saw each step as different
pieces that somehow all formed together to create a working structure.
This theory of nanotechnology was accepted
by many, but scientists knew other definitions and uses of nanotechnology could
