In efforts that may improve diagnoses of many eye diseases, researchers will introduce a new type of laser for providing high-resolution 3-D images of the retina, the part of the eye that converts light to electrical signals that travel to the brain.
Engineers at the Johns Hopkins Urology Robotics Lab report the invention of a motor without metal or electricity that can safely power remote-controlled robotic medical devices used for cancer biopsies and therapies guided by magnetic resonance imaging.
It is possible to manipulate small quantities of liquid using only the force of light, report University of Chicago and French scientists in the March 30 issue of Physical Review Letters .
Georgia Tech researchers have found a way to shrink all the sensing power of sophisticated biosensors — such as sensors that can detect trace amounts of a chemical in a water supply or a substance in your blood — onto a single microchip.
Producing optical images at resolutions as low as one nanometer is the goal of Virginia Tech College of Engineering researcher Yong Xu, who has received a National Science Foundation (NSF) Faculty Early Career Development Program (CAREER) Award.
The National Science Foundation (NSF) has awarded the W. M. Keck Observatory $2 million to improve the sensitivity and resolution of the Keck Interferometer.
A Sandia National Laboratories research team is developing a new type of electrochemical sensor that uses a unique surface chemistry to reliably and accurately detects thousands of differing biomolecules on a single platform.
Researchers at Purdue University have developed a new low-cost system that analyzes scattered laser light to quickly identify bacteria for applications in medicine, food processing and homeland security at one-tenth the ...
A new light microscope so powerful that it allows scientists peering inside cells to discern the precise location of nearly each individual protein they are studying has been developed and successfully demonstrated by scientists at the Howard Hughes Medical Institute's Janelia Farm Research Campus in collaboration with researchers at the National Institutes of Health and Florida State University.
Using materials that flash when struck by certain types of radiation, sensors developed in a new laboratory at The University of Alabama in Huntsville might help doctors treat cancer, customs agents scan for dirty bombs, and scientists study the furthest reaches of the universe.
Producing three-dimensional polymer line structures as small as 65 nanometers wide just became easier with new two-photon absorbing molecules that are sensitive to laser light at short wavelengths, allowing researchers to create them without highly sophisticated fabrication methods.
Specialized pulsed lasers have been used to inject individual cells with a variety of materials, but little is known about how this type of injection might affect living cells.
By combining two techniques, magnetic resonance imaging (MRI) and near-infrared optics, researchers at Dartmouth College and Dartmouth Medical School may have devised a new, potentially more accurate method for diagnosing breast cancer.
Supermarket freezers may soon look a lot brighter while demanding less energy, thanks to LED lighting.
Argonne researchers have successfully laser-cooled and trapped atoms of radium — the first time this rare element has been captured in a magneto-optical trap — with an assist from an unexpected source.
