Nano Robotics- A Discipline of Nanotechnology Engineering
Nanorobotics is one of the most emerging technological fields, which is creating machines or robots whose components are at or close to the scale of a nanometer that is around 10^-9 meters more specifically, Nanorobotics refers to the nanotechnology engineering discipline of designing and building nano robots, with devices ranging in size from 0.1-10 micrometers and constructed of nanoscale or molecular components. Nanorobotics is the future of the technology. The names nanobots, nanoide, nanites, nanomachines or nanomites have been used to describe certain types of devices which are currently under research.
Nano machines are highly used in research, technology, and development, but some primitive molecular machines have been tested as well. One of the best examples of nanomachines is a sensor having a switch approximately 1.5 nanometers. They are capable of counting specific molecules in a chemical sample.
Application of Nano-robotics
One of the first useful application of nano machines might be used in the field of medical technology, which could be used to identify and destroy cancer cells.
Another potential application is the detection of toxic chemicals and the measurements of their concentrations in the environment. Recently, Rice University has demonstrated a single molecule car, which includes the buckyballs for wheels. It is actuated by monitoring the environmental temperature and by positioning a scanning tunneling microscopic tip.
Another application of nanorobotics is that it allows precision interactions with nanoscale objects, or can manipulate with nanoscale resolution. Such devices are more related to microscopy or scanning probe microscopy. By simply following the microscopy definition, with a large apparatus eg. atomic force microscope can be configured to perform manipulation in nanoscales. For this perspective, macroscale robots or micro robots which can move with nano scale precision can also be considered as nano robots.
