Document Summary
Nanotechnology is the application of science at the nanometer scale. A nanometer is one billionth of a meter, and is also the scale at which matter becomes discrete due to its molecular nature. Top-down approach involves trying to make smaller and smaller components. Bottom-up approach seeks to integrate small components (atoms and molecules) to make larger structures. This usually partakes to chemistry, by putting atoms together to make larger molecules. The overlap of these occur at the nanometer scale, and combining them result is in the possibility of creating synthetic systems with complexity approaching that of biological systems. Microelectronics have become a huge industry due to the steady progress in miniaturization of electronic components. Since the 1960"s, microfabrication technology has doubled, resulting in exponential increase in computational power. This general trend in miniaturization was quantitatively predicted in 1965 by. Roger moore, and is referred to as moore"s law.
