Researchers at the University of Washington have developed a method that could make reproducible manufacturing at the nanoscale possible. The team adapted a light-based technology employed widely in biology — known as optical traps or optical tweezers — to operate in a water-free liquid environment of carbon-rich organic solvents, thereby enabling new potential applications.

Researchers take a bottom-up approach to synthesizing microscopic diamonds for bioimaging, quantum computing

Two people operating a laser to heat material and make nanodiamonds.

Researchers at the University of Washington, the U.S. Naval Research Laboratory and the Pacific Northwest National Laboratory discovered that they can use extremely high pressure and temperature to introduce other elements into nanodiamonds, making them potentially useful in cell and tissue imaging, as well as quantum computing.
