System on ChipsNanoelectronics holds the promise of making computer processors more powerful than are possible with conventional semiconductor fabrication techniques.

So here is a caption of Intel's Future Plan!

Display IndustriesA quantum dot display is an experimental type of display technology.

Think of quantum dots as ultra-tiny particles that will make their own light if electricity is applied to them, or if light is shone on them.

That color is directly related to their size, and their color production is extremely stable.

Memory StorageElectronic memory designs in the past have largely relied on the formation of transistors.

Two leaders in this area are Nantero which has developed a carbon nanotube based crossbar memory called Nano-RAM and Hewlett-Packard which has proposed the use of memristor material as a future replacement of Flash memory.

NanoBiotechnology

Study of DNA

Targeting Cancer

Nano Medicine

Brain-Machine InterfaceBrain-machine interface (BMI) is a fabricated system to interpret voluntary brain activity and convert to a mechanical movement

Physiology:Electrical signals in brain → spinal cord → skeletal muscle

DNA StudyDNA molecules, under the influence of an electric field, are forced through nano-scale channels (100 nm) on a “gel biochip”. The molecules deform and stretch to pass through the small channels.

This process separates DNA fragments by length. This is part of the method used to sequence the DNA in the human genome and in identifying a unique DNA “fingerprint”.

The Future

Golden sniffers

Gold nanoparticles are used in a variety of new "sniffers" for cancer and other diseases. As cancerous cells grow, genes and proteins within cells change, and this process emits volatile organic compounds that can be detected--this is why some dogs can be trained to "smell" cancer. Nanoparticles can smell it, too, and in tiny concentrations.

Nano-Art

The promising development of nanotechnology has earned a great deal of admiration from the scientific community. Nevertheless, breakthroughs in nanotechnology are no longer confined to medicine, biology, and engineering. Nano art is an emerging field that allows us to view the tiny world under the microscope from an entirely new perspective.

Color Changing Paint

While experimenting on strings of gold nanoparticles, scientists at the University of California have stumbled upon an astonishing observation. They’ve noticed that the color of gold changes when a string of its particles is stretched or retracted, producing what one of the scientists described as a beautiful bright blue that morphs into purple and then red. The finding has inspired the scientists to create sensors out of gold nanoparticles that change colors when pressure is applied to them.

There is still more that we can expect to happen...

Infinity and beyond...
