NanopartzTM
has developed a
brand new nanomaterial – Gold Nanowires. These nanowires are 30 nm in axial
diameter, and range from 4.5 µm to 6 µm in length.
In the bare form, these nanowires are immersed in DI
water with excess CTAB capping agent to minimize
aggregation. These nanowires can also be
covalently conjugated to our proprietary polymers
terminated with amine, biotin, carboxyl, methyl, or
neutravidin. In these forms, they are delivered in
DI water and purified of CTAB.
Features
-
Highly stable, minimal to no aggregation
-
Conjugation choices to amine, biotin, carboxyl,
methyl or neutravidin
-
Available in aspect ratios from 150 to 200
Benefits
-

wire lengths for nanoelectronics, nanoantennas
-
Applications in tribological additives
-
Light
conduction for digital computers
-

 Tech Note
A01: Properties and Applications of Nanopartz Gold Nanowires
Applications
Uses
Nanowires still belong to the experimental world of
laboratories. However, they may complement or replace carbon
nanotubes in some applications. Some early experiments have
shown how they can be used to build the next generation of
computing devices.
It's possible that semiconductor nanowire crossings will be
important to the future of digital computing. Though there are
other uses for nanowires beyond these, the only ones that
actually take advantage of physics in the nanometer regime are
electronic.
Nanowires are being studied for use as photon ballistic
waveguides as interconnects in quantum
dot/quantum
effect well photon logic arrays. Photons travel inside the tube,
electrons travel on the outside shell.
When two nanowires acting as photon waveguides cross each other
the juncture acts as a quantum dot.
Conducting nanowires offer the possibility of connecting
molecular-scale entities in a molecular computer. Dispersions of
conducing nanowires in different polymers are being investigated
for use as transparent electrodes for flexible flat-screen
displays.
Due to their high Young's
moduli, their use in mechanically enhancing
composites is being investigated. Because nanowires appear in
bundles, they may be used as tribological additives to improve
friction characteristics and reliability of electronic
transducers and actuators.
Because of their high aspect ratio, nanowires are also uniquely
suited to dielectrophoretic
manipulation.
