The
BioPhotonics
Conference
Sep 30, 2021 — Photonics Media will host the first-ever BioPhotonics Conference online Oct. 26-28. Experts in microscopy, spectroscopy, OCT, flow cytometry, and medical lasers will present on topics such as the detection of cancer and viruses, the analysis of...
Saliva Test Instantly Detects Coronavirus with Lasers
BRUSSELS, April 14, 2020 — Responding to the European Commission’s call to tackle the coronavirus pandemic, photonics scientists are developing a new, rapid, noninvasive “optical biosensor” demonstrator that will detect COVID-19 in humans as soon as it is...
Nanocrystal Tags Aid Rapid Pathogen Detection
WEST LAFAYETTE, Ind., and SYDNEY, May 8, 2014 — Tunable nanoparticles could pave the way for screenings that identify thousands of target molecules simultaneously. A team from Purdue University and Macquarie University used tunable luminescent nanocrystals as tags, applying them to high-speed...
Laser Technique Diagnoses Meningitis
GLASGOW, Scotland, Feb. 14, 2014 — A new laser-based test uses nanoparticles to speed up the diagnosis and treatment of bacterial meningitis, a disease that can lead to blood poisoning and brain damage if not discovered quickly.
Laser, Electric Fields Combined for Novel Lab-on-a-Chip Technology
WEST LAFAYETTE, Ind., July 7, 2011 — New technologies that combine a laser with electric fields promise new lab-on-a-chip designs for manipulating bacteria, viruses and DNA in a range of potential applications. A new method, dubbed “hybrid optoelectric manipulation in...
Microscope Beats Diffraction Limit
MANCHESTER, England, March 3, 2011 — A microscope created by scientists at the University of Manchester shatters the record for the smallest object the eye can see, beating the diffraction limit and likely helping to elucidate the causes of many viruses and diseases. Experimental...
Laser Strips, Hollows Out Atoms
MENLO PARK, Calif., June 30, 2010 — The world’s brightest x-ray source has been used to strip neon atoms of all their electrons, and also to create "hollow" atoms, which are devoid of only their innermost electrons. The first published scientific results from the hard x-ray...
New Method Manipulates Particles
WEST LAFAYETTE, Ind., June 22, 2010 — Researchers at Purdue University have developed a potential new tool for medical diagnostics, for testing food and water for contamination and for crime scene forensics. The novel technique uses a combination of light and electric fields to position...
Light Kills Germs
Urbana-Champaign, Ill. Jan. 21, 2010 - In the battle against bacteria, researchers at the University of Illinois are using visible light to destroy harmful bacteria and viruses, even in the dark. Based upon a new ca...
Microbes Beware
Apr 1, 2008 — Your throat is parched, and you could drink a gallon of water, but you’ve just arrived at a faraway destination where the local water quality comes with no guarantees. Do you: 1) Gulp down the water anyway and risk days of gut-wrenching agony...
Sharon Weiss Receives NSF Award for Waveguide Research
Mar 27, 2008 — Sharon M. Weiss, PhD, assistant professor of electrical engineering and physics at Vanderbilt University, will receive $400,000 over five years under a National Science Foundation (NSF) Faculty Early Career Development Award. The CAREER Award will...
Images Reveal Details of Viral Assault
Aug 20, 2004 — ARLINGTON, Va., Aug. 20 -- Using a combination of imaging techniques, researchers have determined the mechanics that allow some viruses to invade cells by piercing their outer membranes and digesting their cell walls. The researchers combined their...
