Engineering nanotechnology is a new area within nanotechnology where mechanical engineers were poised to make the greatest contributions and to change engineering education to address the new challenges that nanoscale technology represents.
Engineering nanotechnology, indeed, may change the way we think about mechanical engineering altogether, making it a more multidisciplinary field, one as concerned with atomic-level effects as electrical engineering or chemistry is.
Engineering nanotechnology is based on the fact that when solids, liquids, and gases are confined to regions smaller than 100 nm, for instance, their behavior can be modified by the confinement. Properties such as thermal conductivity, electrical conductivity, optical absorption and emission spectra, mechanical strength, and viscosity are size dependent.
Many researchers in engineering nanotechnology envision that material organized at this scale could form the basis for structures, devices, and systems that could have tremendous impact on parts of the economy as diverse as information, energy, health, agriculture, security, and transportation.
Nanotechnology engineers see possibilities for data storage at densities greater than one terabit per square inch; for high-efficiency, solid-state engines; for analysis of single cells that could form the basis for diagnosis of complex diseases such as cancer; and for ultralight and ultra strong materials for vehicles.
