The technology, which may someday be as portable as a smartphone, promises faster and more accurate measurements of radiation exposure, potentially saving lives...
Using an electron beam to image the tiniest of defects and patterns on microchips, the scanning electron microscope (SEM) has long been a mainstay of the...
Using strands of DNA to create miniature hinges that pop open or shut when binding to specific molecules, researchers at the National Institute of Standards and...
Frequency combs — specialized lasers that act like rulers to measure light — are now being brought down to a low-power, chip-scale form. NIST researchers David...
Devices that capture the brilliant light from millions of quantum dots, including chip-scale lasers and optical amplifiers, have made the transition from...
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized time keeping, the...
When testing a new medicine, researchers must do more than assess how well that drug works. They also have to determine whether the medicine has some negative...
In research, sometimes the bumpy path proves to be the best one. By creating tiny, periodic bumps in a miniature racetrack for light, researchers at the...
Researchers at the National Institute of Standards and Technology (NIST) have developed chip-scale devices for simultaneously manipulating the color, focus...
In two new studies, researchers at the National Institute of Standards and Technology (NIST) have greatly improved the efficiency and power output of a series...
The biosensor, developed by researchers at NIST, Brown University and the French research institute CEA-Leti, identifies biomarkers by measuring how binding...
The ability to transmit and manipulate the smallest unit of light, the photon, with minimal loss, plays a pivotal role in optical communications as well as...
Trapped in a microscopic cage made of strands of DNA, molecules of a life-saving drug course through the bloodstream of a cancer patient. Only when receptors on...
Cutting intricate patterns as small as several billionths of a meter deep and wide, the focused ion beam (FIB) is an essential tool for deconstructing and...
Atoms are notoriously difficult to control. They zigzag like fireflies, tunnel out of the strongest containers and jitter even at temperatures near absolute...
Shine a flashlight into murky pond water and the beam won’t penetrate very far. Absorption and scattering rapidly diminishes the intensity of the light beam...
Five hundred million years ago, the oceans teemed with trillions of trilobites — creatures that were distant cousins of horseshoe crabs. All trilobites had a...
To combat COVID-19 amid supply shortages in 2020, health care facilities across the U.S. resorted to disinfecting personal protective equipment (PPE), such as...
