What is Nanorobotics?

Nanorobotics is the emerging technology field creating machines or robots whose components are at or close to the scale of a nanometer.
More specifically, nanorobotics refers to the nanotechnology engineering discipline of designing and building nanorobots, with devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or molecular components.

Nanomachines are largely in the research-and- development phase, but some primitive molecular machines have been tested. An example is a sensor having a switch approximately 1.5 nanometers across, capable of counting specific molecules in a chemical sample.

Nanomedicine

The first useful applications of nanomachines might be in medical technology, which could be used to identify and destroy cancer cells.

The joint use of nanoelectronics, photolithography, and new biomaterials provides a possible approach to manufacturing nanorobots for common medical applications, such as for surgical instrumentation, diagnosis and drug delivery.
Practical nanorobots should be integrated as nanoelectronics devices, which will allow tele-operation and advanced capabilities for medical instrumentation.

Nubot is an abbreviation for “nucleic acid robot.” Nubots are organic molecular machines at the nanoscale. DNA structure can provide means to assemble 2D and 3D nanomechanical devices. DNA based machines can be activated using small molecules, proteins and other molecules of DNA.

Nano Transistors

A nanotransistor is transistor the component that acts as an electronic signal switch or amplifier – that is near the scale of a billionth of a meter (or nanometer) in size.
Although there is currently no transistor of this scale in practical use, a number of approaches toward achieving such a remarkable component of nano’ ?chnology appear promising.
