Nanotechnology
Nanotechnology is a multidisciplinary field that combines science and technology to control and create matter on the molecular level.
Technically,materials and devices measured in nanometers of 100 nm and under are nanotechnology whether they are created using bottom-up or top-down method of creation.
Bottom-up builds materials and devices from their molecular components using chemical self-assembly through the principle of molecular recognition.
Molecular recognition is either static or dynamic.
Static molecular recognition is a singular reaction between a "host" molecule and a "guest" molecule that forms a joined complex.
The first binding between an initial "guest" and a site on the "host" is continued automatically with subsequently introduced "guests" onto subsequent binding sites on the host.
Dynamic molecular recognition can be positively allosteric or negatively allosteric,which either sets an increasing association with the subsequent binding of each guest in the case of the positive and a decreasing association with the binding of each subsequent guest.
Top-down nanodevices are created by reducing the size of larger
than nanoscale devices using sophisticated analytical tools
including electron beam lithography,atomic force microcopy,
scanning tunneling microscopy,and molecular beam epitaxy.
Nanotechnology has virtually infinite future applications
including new nanodevices in application in electronics and
medicine.Currently,few nanotechnology centric applications and
products are truly commercial but the early commercial products
include a variety of coatings,fabrics,gels,and lotions.
A few applications that have been successfully trialed include
nanoscale solar cells.Through governmentally sponsored funding,
University of California scientists have used semiconductor
nanorods with polymers for extremely efficient solar cells.
Light absorption and photocurrent generation is nanoscale in
nature,making solar cells of superior performance over
conventional materials and fabrication techniques.
Nanofabrication is also successfully used for many different
medical and therapeutic applications such as biometric sensors.
Although fully nanotechnology based devices have not expanded
into their commercial potential,multiple industries have
benefited tremendously from components or base materials created
using nanotechnology.Nanowires are used in semiconductor
fabrication for electron beam lithography,atomic layer
deposition,and molecular vapor deposition.
Despite the almost unlimited potential for nanotechnology to
transform many different industries,material science experts are
increasingly becoming vocal about the narrow approach that is
permeating all technologies in nanoscale.Although nanotubes,
nanowires,and nanoparticles are widely being integrated into a
multitude of commercially viable industries,the truly
transformative fundamental nanotechnology concepts are failing to
leave the lab.
