Angle-resolved low coherence interferometry (a/LCI) directly measures diagnostically relevant sub-cellular features in epithelial tissues up to 500 μm below the surface. Unlike...
Multispectral extended near-infrared (exNIR) optical imaging is enabling deeper in vivo optical imaging, thanks to new indium gallium arsenide (InGaAs) sensors. The label-free...
Low cost was a theme at the 2013 Society for Neuroscience annual meeting (November 9–13, San Diego, CA), as vendors demonstrated their responses to the effect of funding cuts ...
A new market research report from BCC Research (Wellesley, MA) values the 2012 global market for flow cytometry products at $3.1 billion and predicts that it will reach nearly...
The Mid-InfraRed Technologies for Health and the Environment (MIRTHE) Center at Princeton University (Princeton, NJ) has received a planning grant proposal from the National Science...
The European Photonics Consortium (EPIC) celebrated its 10th anniversary on December 13, 2013, with the help of 160 supporters from 26 countries at a dedicated event in Brussels...
At its 2013 annual meeting (New Orleans, LA; December 14-17), the American Society for Cell Biology (ASCB) chose to highlight a discovery, enabled by optics, that answers a century...
Just about a year ago, in January 2013, an article in Genetic Engineering and Biotechnology News asked, "when will DNA sequencing fully expand from research tool to routine clinical...
Do you wish people in general -- and politicians in particular -- had a better appreciation of light and the technologies that harness its potential? Well, the United Nations ...
A bandage-like patch of polymer microneedles, paired with surface-enhanced Raman scattering (SERS), may enable a future method for safe and painless testing for drugs and some...
A new noninvasive approach to blood glucose monitoring uses photoacoustic spectroscopy (PAS): a painless pulse of laser light, applied externally to the skin, is absorbed by glucose...
Researchers at École Polytechnique Fédérale de Lausanne (EPFL) have developed an optical method for accurately determining the toxicity of nanomaterials.
Most microscopy approaches produce 3D imagery by scanning the depth of a sample, which is problematic for optically sensitive or fast-moving samples. But a simple, new technique...
Synchrotron x-rays boost the quality of medical imaging and lower doses of radiation compared to x-ray devices currently used in hospitals worldwide. But synchotron x-ray devices...
Scientists at Harvard University's School of Engineering and Applied Sciences (SEAS) and Wyss Institute for Biological Engineering (Cambridge, MA) have used laser illumination...
Using a multiphoton laser technique, researchers at Chalmers University of Technology (Göteborg, Sweden) and the Polish Wroclaw University of Technology (Wroclaw, Poland) have...
A new optical coherence tomography (OCT) device about the size of a handheld video camera could enable primary care physicians to detect retinal diseases -- including diabetic...
While conducting experiments for his doctoral thesis in 1969, Robert Alfano discovered the white-light supercontinuum laser—and was sure he'd made a mistake. "For three months...
