Description

The world is heading towards a society where every single parameters associated with our life are entangled and when several parameters vary at a time, it is impossible to model it. Ironically, this is the basis of brain-like computing —stopping robotics to revolutionize medical science. We are designing and synthesizing intelligent nano-platform, which could process thousands of decisions at a time, moreover, we do not need power supply, our machines get energy from environment kT. Our basic architectural model is a dendrimer and computational model that it will carry out massively parallel operations is cellular automation. Following step-by-step organic synthesis we attach sensors, central control, processing region and finally execution channel with specially designed molecular machines, —such a concept was only a fiction earlier. Four ground breaking results we are investigating, (i) convert available thermal energy into mechanical energy, as a remarkable solution to energy crisis. (ii) The nano-machine is designed to discriminate normal cells and cancer cells and selectively suppress cancer cell growth, or engage into the physical process of tuning fundamental molecular protein route physically. (iii) To solve Alzheimer's syndrome like several neurodegenerative diseases breaking apart beta-plaque. (iv) Massively parallel computing using the nano-platform for nano-brain.
