ScienceDaily: A new power-free microfluidic chip developed by researchers at the RIKEN Advanced Science Institute (ASI) enables detection of microRNA from extremely small sample volume in only 20 minutes. By drastically reducing the time and quantity of sample required for detection, the chip lays the groundwork for early-stage point-of-care diagnosis of diseases such ...

Azonano: "We believe our microactuator is more efficient and powerful than any current microscale actuation technology, including human muscle cells," says Berkeley Lab and UC Berkeley scientist Junqiao Wu. "What's more, it uses this very interesting material—vanadium dioxide—and tells us more about the fundamental materials science of phase transitions."

Wu is corresponding author ...

SpectraFluidics, the innovator in high performance trace chemical vapor detection and analysis systems, has demonstrated the repeatable performance capabilities of their novel sensor platform when used to detect DNT, an important chemical marker associated with TNT explosives.

SpectraFluidics' patented technology combines SERS with free-su...

MedGadget: In an attempt to miniaturize and speed up testing of large numbers of chemical reactions for potential drug candidates, scientists at UCLA have developed a new microfluidic device capable of performing 1,000 simultaneous in situ click chemistry reactions, which can identify chemicals that bind to proteins. Because enzyme reagents required for in sit...

Engadget: It's hard to find a good specialist on earth, let alone when you're floating 240 miles above it. That's why NASA will test the Microflow, a breadbox-sized device that instantly detects cancer and infectious diseases, and can even sense the presence of rotten food. The Canadian-made device is a "flow cytometer," which works by analyzing microparticles in blood or other fluids and replaces hospital versions weighing hundreds of pounds. Here on Earth, the device could let people in rem...
