Nano- and microengineering are the fundamental theory engineering practice and leading-edge technologies in analysis design optimization and fabrication of NEMS and MEMS nano- and microscale structures devices and subsystems. The studied nano- and microscale structures and devices have dimensions of nano- and micrometers. To support the nano- and microtechnologies basic and applied research and development must be performed. Nanoengineering studies nano- and microscale-size materials and structures as well as devices and systems whose structures and components exhibit novel physical electromagnetic and electromechanical chemical and biological properties phenomena and processes. The dimensions of nanosystems and their components are 10-10 m molecule size to 10-7 m that is to 100 nanometers. Studying nanostructures one concentrates one s attention on the atomic and .
