Near-Infrared Wavelength Specificity Yields Phototherapy Insights
ARLINGTON, Texas, June 19, 2023 — Transcranial photobiomodulation (tPBM) is an emerging form of light therapy that uses LEDs or low-intensity lasers that emit near-infrared (NIR) light to stimulate the brain. Although tPBM is in the early stages of development, it shows promise as a potential therapy for enhancing cognitive function and treating neurophysiological disorders. To deepen scientific understanding of tPBM, researchers at The University of Texas at Arlington (UTA) investigated its effects on the hemodynamic and
Optical Biopsy System Cuts Potential for Misdiagnoses of Liver Cancer
WASHINGTON, D.C., Jan. 18, 2022 — An optical biopsy system that combines diffuse reflectance spectroscopy and fluorescence lifetime measurements can distinguish between cancerous and healthy tissue in the liver. The technology could make it easier to diagnose liver cancer, which is...
Raman Spectroscopy and Machine Learning Team Up to Predict Immunotherapy Response in Patients
BALTIMORE, Oct. 21, 2021 — Using Raman spectroscopy and machine learning, a team at Johns Hopkins University developed a noninvasive technique to assess how cancer patients will respond to immunotherapy. The researchers used Raman spectroscopy to map the biochemical...
Leibniz Institute Observes Neuronal Structures with Holography
JENA, Germany, Nov. 29, 2018 — Using a multimode optical fiber as thin as a human hair, scientists at the Leibniz-Institute of Photonic Technology have observed at high resolution the neuronal structures inside deep brain areas of living mice. The researchers drew on holographic...
Fiber Optic Technique Aids Muscle Impairment
Mar 31, 2017 — Muscle biopsies — a procedure that removes a small sample of tissue for lab testing and is often used to diagnose and treat a wide range of movement disorders — can be painful and invasive. And it can take weeks to get the results. Now,...
Optical Probe Bridges Gender Gap
EVANSTON, Ill., July 22, 2010 — A team led by a Northwestern University biomedical engineer has found that combining novel optical technologies with a common colon cancer screening test may allow doctors to more accurately detect the presence of colon cancer, particularly in...
Tiny Biosensor to Detect DNA
TEMPE, Ariz., March 26, 2008 -- A biosensing nanodevice powered by a tiny enzyme motor may one day eliminate long airport security lines and revolutionize health screenings for diseases such as anthrax and cancer and antibiotic-resistant Staph infections. Arizona State...
