Diagnose diseases more quickly and easily
17-Mar-2023
Despite recent advancements, many highly sensitive diagnostic tests for viral diseases still require complicated techniques to prepare a sample or interpret a result, making them impractical for point-of-care settings or areas with few resources. But now, a team reporting in ACS Central Science ...

LMU physicists led by Ralf Jungmann introduce an entirely new approach to super-resolution microscopy: Tiny ‘blinkers’ enable simultaneous imaging of multiple biomolecules. In everyday life, blinking lights can send signals – for example, that a car is going to turn. Now, researchers have ...
Understanding cell behavior better by elucidating how proteins work with cell membranes
28-Jan-2019
Trillions of cells -- all different shapes and sizes -- form a human body's structure. Surrounding each cell is a membrane, jointly acting as hostess and security -- welcoming certain information into the cell while making sure its components don't spill out into the body's void. Much is known ...
RNA changes mark old blood cells among new ones, foiling self-transfusions
22-Oct-2018
A Duke University research team has found a way to help sporting officials detect whether an athlete's blood has been doped by an infusion of their own stored blood. While tests have been developed to detect two of the three most common methods of dramatically boosting the oxygen-carrying ...

Researchers at McMaster University have established a way to harness DNA as the engine of a microscopic "machine" they can turn on to detect trace amounts of substances that range from viruses and bacteria to cocaine and metals. "It's a completely new platform that can be adapted to many kinds of ...

When cancer spreads from one part of the body to another, it becomes even more deadly. It moves with stealth and can go undetected for months or years. But a new technology that uses "nano-flares" has the potential to catch these lurking, mobilized tumor cells early on. "We've taken perhaps the ...
Columbia researchers develop a general optical imaging platform to examine activities of a broad range of small biomolecules in living cells and animals
04-Mar-2014
Researchers at Columbia University have made a significant step toward visualizing small biomolecules inside living biological systems with minimum disturbance, a longstanding goal in the scientific community. In a study published March 2nd in Nature Methods, Assistant Professor of Chemistry Wei ...

Research describes the development of a portable device that can extract HIV viral RNA from whole human blood to produce a purified and thermally-stable sample without the use of electric power. The technology has the potential to enable accurate monitoring of patient response to HIV treatment in ...
