This represents a significant step forward in "directed assembly," where scientists build minute structures by specifying starting conditions and letting physical and chemical processes do the assembly work, instead of doing it themselves.
By changing its shape and binding to consecutive parts of the tube's surface, these natural molecules are able to travel as far as a micrometer (1,000 nanometers) by taking steps of 8 nanometers at a time.
Chemical engineers at Rice University have found a new catalyst that can rapidly break down nitrites, a common and harmful contaminant in drinking water that often results from overuse of agricultural fertilizers.
A team of researchers from MIT and Brigham and Women's Hospital has developed a new type of nanoparticle that could afford patients the choice – potentially making uncomfortable injections a thing of the past.
Bandyopadhyay created a nanoscale infrared detector, which could reduce car crashes by allowing vehicles to sense each other in darkness, detect land mines, and monitor global warming. Unlike other infrared sensors, it operates at room temperature.
Atomic layer deposition is one of many techniques for applying thin films, which can improve computer memory, protect materials against corrosion, oxidation, and wear, and perform as batteries when deposited directly onto chips.
