Nanotechnology refers to the science and engineering activities at the level of atoms and molecules.
Nano-robots are the robots that are simply known as those controllable machines at the nano meter or molecular scale, composed of nano-components. Nanorobots would constitute any “smart” structure capable of actuation, sensing, signaling, information processing, intelligence, manipulation and swarm behavior at nano scale.
More specifically, nano robotics refer to the still largely hypothetical nanotechnology engineering discipline of designing and building nano robots. Nanorobots are designed to perform a specific task with precision at nanoscale dimensions.
Assembly and realization of nano-robots depend on the principles of molecular nanotechnology and mechanosynthetic chemistry. Nanorobots are programmable assemblies of nanometer scale components constructed by manipulating macro/micro devices or by self-assembly on pre-programmed templates or scaffolds.
Nanorobots have chemical sensors which detect the target molecules. As a response they would emit a power signal proportional to the detected amount. This signal would arrive to a programmed microprocessor which controls the direction and velocity of the nanorobot.
Nanorobots need energy to carry out different manipulations such as propulsion, force, actuation, communication or any other activity in the biological system at nano-scale. This energy can be generated by natural (biological) or artificial (chemical) entities known as molecular motors, which when perform at nano-scale are known as Nanomachines.
Nanorobotics provides novel techniques for exploring the biodomain by manipulation and characterization of nanoscale objects such as cellular membranes, DNA and other biomolecules. Nano tools, sensors and actuators can provide measurements and/or movements that are calculated in nanometers, gigahertz, piconewtons, femtograms, etc., and are promising for molecular machines and bio- and nanorobotics applications.
