“Nanotechnology is the application of science to control matter at the molecular level”

“Nanotechnology is the application of science to control matter at the molecular level”. It is the ability to develop the different properties and phenomena at that scale as compared to those properties with single atoms or molecules or bulk behavior. The massive growth in nanotechnology results in opening novel fundamental and applied frontiers in the science of materials and engineering, bionanotechnology, quantum dots, surface-enhanced Raman scattering (SERS), and applied microbiology. Recent Developments in the organization of nanoscale structures into advanced superstructures ensure that nanotechnology will play a critical role in many key technologies. It is gaining importance in various areas such as mechanics, optics, biomedical sciences, chemical industry, electronics, space industries, drug-gene delivery, energy science, catalysis, optoelectronic devices, photoelectrochemical applications, and nonlinear optical devices.
