Nanotechnology is an emerging field of research and development dedicated to increasing the control over material structures of nanoscale size (0.1 to 100nm) in at least one dimension. Nanotechnology is also a cluster of emerging techniques from solid-state technology, biotech., chemical technology and scanning-probe technology that converge “top-down” and ”bottom-up” to the nanoscale.
Today, nanotechnology consists of four major fields: nanoelectronics, nanometerial, molecular nanotechnology, and nanoscale-resolution microscopes. Although the boundaries are fuzzy, these field represent different enabling technologies creating their own opportunities.
