Nano engineering and Nano Technologies

Smart materials are defined as materials with properties engineered to change in a controlled manner under the influence of external stimuli. Some of the external stimuli are temperature, force, moisture, electric charge, magnetic fields and ph. The self-assembly of peptides has enormous applications in the fields of medicine and electronics. Bio-inspired engineered systems have been designed based on the mechanistic perceptions obtained from natural systems for novel self-assembled structures.  In the biological system, each cell type is programmed to display different levels of smartness.
