Nanotechnology is the understanding and control of matter at dimensions between approximately 1 and 100 nanometers (nm), where unique phenomena enable novel applications not feasible when working with bulk materials or even with single atoms or molecules. A nanometer is one-billionth of a meter. A sheet of paper is about 100,000 nanometers thick; a single gold atom is about a third of a nanometer in diameter.
Researchers seeking to understand the fundamentals of properties at the nanoscale call their work nanoscience; those focused on effective use of the properties call their work nanoengineering.
Encompassing nanoscale science, engineering, and technology, nanotechnology involves imaging, measuring, modeling, and manipulating matter at the nanoscale.
Stay tuned for the next cycle of the EnvisioNano and Student Video Contests. Winning images will be showcased on Nano.gov and displayed at TechConnect World Innovation 2015; the winning video will be shared on the NNI's YouTube channel and on Nano.gov
