FEATURES
OCT Moves from Clinic to OR to . . . Home? Optical coherence tomography has proved its worth in the physician’s office, but now it wants to make inroads into the surgical suite as well – and possibly beyond. Optical coherence...
Dynamic Phase-Shifting Microscopy Tracks Living Cells The ability to instantaneously measure live cells – and follow motions and processes over time – helps researchers study dynamic cell behavior. Using harmless light levels – and...
Maldi-MS Making a Strong Comeback From cancer diagnosis and prognosis to the effects of applying medical leeches, the applications of Maldi imaging are growing. Higher throughput and a wider choice of instruments such as solid-state...
Nanoparticle Tracking Analysis Characterizes Biomaterials Biomaterial characterization at the nanoscale is gathering interest, as a better understanding of properties such as particle size or number may provide new ways to look at nanotoxicology or provide...
EDITORIAL
Is the Fountain of Youth Made of Light? The World Health Organization’s World Health Day 2012 has come and gone (April 7), but its theme, “Good health adds life to years,” is one we all can appreciate. It also is a message that may well have special significance for the biophotonics community, promising opportunities for new research, treatments and medical devices aimed at making our lives better as we age....

Liquid lasers detect cancer genes Genes linked to cancer and other diseases may now be simpler to detect with a new liquid laser technique that clearly distinguishes between mutated and healthy DNA. Researchers at the University of Michigan say their method works better than the current approach, which uses fluorescent dye and other biological molecules to find and bind to mutated DNA strands. Their findings were reported in...
Morpho butterfly wings inspire thermal imagers Mother Nature's 5 million year old butterfly design has led to the development of a bio-inspired sensor that is faster, smaller and more sensitive than today's thermal imaging devices. Dr....

Polarization vision keeps cuttlefish safe Cuttlefish may be colorblind, but they can see things we can’t – in fact, they have the most acute polarization vision yet found in any animal. And that special power gives them an advantage in survival and hunting situations. “Just like color and intensity, polarization is an aspect of light that can provide animals with information about the world around them,” said...
