Researchers ink nanostructures with tiny 'soldering iron'

Researchers have shed light on the role of temperature in controlling a fabrication technique for drawing surface chemical patterns as small as 20 nanometers. This technique could provide an inexpensive, fast route to growing and patterning a wide variety of materials on surfaces for the fabrication of electrical circuits and chemical sensors, or for the study of how pharmaceuticals bind to proteins and viruses.
