BiNano provides information on the application of nanotechnology to electronics and computing. Future applications will extend to organic electronic components that are grown using methods more similar to biological processes than the etching, crystalline growth, or directed molecular assembly methods that are currently in use.
Nanotechnology is the science and application of forming objects
on a level tinier than 100 nanometers. The extreme vision of nanotechnology
is the "bottom up" production of virtually any substance or object by assembling
one atom at a time. Although nano-tech processes transpire at the scale
of nanometers, the elements and objects that result from these processes
can be much more massive. Large-scale results happen when nanotechnology
involves enormous orchestration in which several concurrent and synergistic
nanoscale processes combine to create a large-scale result.
Objects produced using nanotechnology generally have unique characteristics such as super conductivity, high strength relative to their weight, low friction, high thermal insulation properties, specific beam frequency selectivity, quantum effects, extreme water repellence, and self-assembling geometric patterns such as nanotubes, nanospheres and nanoctagons.
Nanotechnology inspires the imagination, but not all visions of the future of nanotechnology are pleasant. Images of nanotechnology in movies, television, and the popular press sometimes involve reproducing nanobots that have gone awry in a growing sea of gray sludge. However, in real life nanotechnology is much more likely to keep your clothes free from wrinkles than to take over your city. Nonetheless, many scientists take these concerns seriously and are working to insure that the fruits of nanotechnology are safe and positive. Other Nanoforum - European Nanotechnology Gateway. Before further discussion of nanotechnology products and services, we should provide an overview of the core geometry of various nanostructures. Nanocomposites blend substances such as polymers and ceramics in a blended mixture of nanosize proportions. Nanospheres and nanocircles are circular structures, between 1-100 nanometers in scale, that are used to -- absorb, transport, and diffuse mass; absorb and reflect specific wavelengths of light or other energy; and perform as very small ball bearings for low-friction coatings. Nanocrystals are the general term for complex, polygonal nanostructures that are grown rather than assembled atom by atom. Nanocrystals can have high strength and low weight compared to customary matter. Nanocrystals can additionally have one-of-a-kind electromechanical characteristics and produce light from electricity with more efficiency than incandescent lights. Nanotubes, one category of nanocrystals, are formed of one or more concentric, hollow, cylindrical carbon micro-scale materials with hexagonal, octagonal, or circular caps. Quantum dots are a version of nanocrystal with separate energy states at the atomic scale. Quantum dots can emit a much narrower band of wavelengths than they absorb.

There are numerous applications for nanotechnology in the area of electronics and computing. Nanochips will likely be made by stringing individual atoms together into electronic components or grown using nanocrystalline processes. For example, one may scratch lines in silicon substrate using an Atomic Force Microscope, spread polymer over these lines, apply heat and electricity to make wires, and then engineer them into circuits. Nanocomputers with pieces less than 100 nanometers in scale and quantum memory will greatly decrease computing heat and increase computing velocity. And Home Virtual Reality Tours. Nanotechnology is already being used for numerous games and recreation related usages. For example, nanotechnology tennis rackets and golf clubs are lighter, stronger, and will generally be designed to deliver more motion control. Nanotech sealants on swim suits repel water, reduce friction with the water, and enable swimmers to go faster.
There are hopeful usages of nanotechnology in the discipline of orthopedics. Grafts of natural bone will likely carry disease or trigger immune rejection by the host. If one sterilizes the bone to reduce the chances of pathology, then this can weaken the bone. Artificial bone cement without nanotechnology can work for tiny uses, but tends to not have enough strength for load-bearing bone replacement. However, fabricated bone paste made with nanoceramic particles shows considerable promise for bone repair and replacement, even in load-bearing usages. Additional Nanobase. Nanotechnology could one day be able to generate nanomedibots that function like fabricated white-blood cells – repairing tissue at a nanoscale plane. We have already said that nanocapsules may transport and release pharmaceuticals. They will likely furthermore contain living cells that release therapeutic agents, protecting the cells from rejection or destruction by the host by camouflaging them from the host’s immune system. Some day there may even be nanotech blood vessels for implantation in people with cardiovascular sickness. See also Virtual Reality Links.
