Developing drugs to combat or cure human disease often involves a phase of testing with mice, so being able to peer clearly into a living mouse's innards has real value. But with the fluorescent dyes currently used to image the interior of laboratory mice, the view becomes so murky several millimeters under the skin that researchers might have more success divining the future from the rodent's entrails than they do extracting usable data. Now Stanford researchers have developed an improved...

A team of researchers has integrated tiny detectors capable of counting individual photons on computer chips. These detectors, called "single-photon avalanche diodes (SPAD)," act like mini Geiger counters, producing a "tick" each time a photon is detected. The researchers present their findings in Applied Physics Letters, a journal published by the American Institute of Physics. "In the past, making these detectors required specialized processes, but recently there has been tremendous...

BRIDGEWATER, N.J., March 1, 2011 /PRNewswire/ -- Hamamatsu Photonics has introduced the new Quantaurus series of compact instruments for measuring the properties of photoluminescent materials. The new Quantaurus-Tau measures fluorescence lifetimes as short as 100 picoseconds, while the Quantaurus-QY measures quantum yields faster and more easily than the traditional relative measurement method. The combination of these two instruments enables a comprehensive characterization of...

Accidental damage to thin or buried nerves during surgery can have severe consequences, from chronic pain to permanent paralysis. Scientists at the University of California, San Diego School of Medicine may have found a remedy: injectable fluorescent peptides that cause hard-to-see peripheral nerves to glow, alerting surgeons to their location even before the nerves are encountered. The findings are published in the Feb. 6 advance online edition of the journal Nature Biotechnology. Nerve...

Fluorescent microscopy makes use of molecules, such as green fluorescent protein (GFP), that emit colored light when illuminated with light of a specific wavelength. Molecules like GFP can be used to label proteins of interest and can reveal information about the relationships of molecules within cells. Fluorescence polarization, also known as anisotropy, is specific parameter of fluorescence that can provide additional information about the properties of individual molecules. Fluorescence...
