Researchers at Harvard's Wyss Institute for Biologically Inspired Engineering and Harvard Medical School have developed a method that combines the team's DNA-powered imaging technology with a single-molecule labeling strategy at a desired location within synthetic nanostructures or intact cells. This approach could allow researchers to stimulate or inhibit the functions of individual molecules in real time and with very high resolution.
Platinum is one of the most commonly used catalysts for fuel cells, but its high cost has spurred research efforts to find ways to use smaller amounts of it while maintaining the same catalytic. Now researchers at the Georgia Institute of Technology have demonstrated that films of platinum only two atoms thick supported by graphene could enable fuel cell catalysts with unprecedented catalytic activity and longevity.

Researchers Sandia National Laboratories have developed a nanoantenna-enabled detector that can boost the signal of a thermal infrared camera by up to three times and improve image quality by reducing dark current — a major component of image noise — by 10 to 100 times. A nanoantenna is a nanoscale antenna-like structure that sends and transmits electromagnetic waves.

Researchers at the University of Pennsylvania have shown how a fuel cell can be built with monodisperse platinum-cobalt nanocrystals – a scientific advance that could pave the way for making fuel cell technology more stable and cost-effective.

Researchers at Penn State have developed a field-effect transistor that is made of 2D materials and that is more energy efficient and produces less heat than field-effect transistors used in current computers. This new transistor is inspired by how the brain works and provides a range of probabilistic responses instead of “on” or “off” responses.

A chameleon can alter the color of its skin by using periodic optical nanostructures, called photonic crystals, in its skin. So far, scientists have made versions of a photonic crystal "smart skin" that changes color in response to the environment, but the sizes of these versions of “smart skin” also change. This time, chemists at Emory University have developed a flexible smart skin that reacts to heat and sunlight while maintaining a near constant volume.
