ABSTRACT
Biologically inspired nanorobots are known as bionanorobots. This is another research field for the development of nanorobotics by creation of artificial biological systems–both engineered viruses and bacteria. The use of pulses is operationally simple and effective and can function in a wide range of artificial rotary and linear nanomotors. The design of a nanorobot requires an autonomy swimming and navigation strategy for overcoming the low Reynolds number viscous drag and Brownian motion. Nubots are nanorobots designed from nucleic acids. An amoeba-like shape-changing nanorobot has been developed consisting of assembled biomolecules and nanomotors, such as proteins and nucleic acid. The combination of nanomotor with electromechanical actuators and an incorporated biosensor element is a novel platform for inventing the next generation of advanced nanomachines and nanorobotics. The propulsion mechanism of acoustic nanorobots is due to their use of asymmetric steady streaming to produce a finite motion speed along the axis of symmetry of the nanodevice and perpendicular to the oscillation direction.
