AI Accelerates Skin Lesion Identification Historically, the gold standard for diagnostics in dermatology has been histopathology, which is the examination of tissues and cells under a microscope. The tissue sample that is extracted from the...
Optical Coherence Tomography Noninvasively Images Skin Structure The skin is the largest organ of the body, serving as a protective layer against environmental factors that include infection, ultraviolet radiation, and temperature fluctuations. The skin is...
Assessing the Extent of Laser Skin Damage Lasers are currently used in many skin care applications, both medical and cosmetic. However, it is important to ensure proper handling and monitoring of the laser source to avoid damage to the skin...
Raman Spectroscopy-Based Detection of Skin Cancer to Guide Surgery A research team at the University of Nottingham has developed an autofluorescence-Raman spectroscopy technique that aims to streamline surgery to remove skin cancer. The technique has been trialed at...
Editorial
A sharper view of skin conditions For the trained clinician, an experienced eye can provide guidance to address developing skin conditions. But for doctors like Elaine Gilmore, a practicing dermatologist for 15 years who has seen skin cancer cases rising, the final answer usually comes from histopathology — the identification of cells and tissues under a microscope. Given that this is labor-intensive and time-consuming, imaging...

Gamma Light, Sound Could Lessen Neurodegenerative Effects An MIT study shows how 40 hertz (Hz) sensory stimulation with light and sound helps sustain myelination, an essential process in the brain that insulates the signal-sending branches of neurons,...
Squishy Lasers Could Reveal Secrets of Cell Growth Origins Researchers at the University of St. Andrews and the University of Cologne have developed lasers that they have described as “squishy.” These devices could help solve the biological...
Sivers Semiconductors to Spin off Photonics Business Sivers Semiconductors has entered into a non-binding letter of intent to merge its Sivers Photonics Ltd subsidiary with byNordic Acquisition Corporation, a publicly traded special purpose acquisition...
Optical Magnetometers Measure Indicators of Disease A wearable optical device that records activity in the autonomic nervous system could provide medical professionals with a tool for detecting early signs of physical stress. The device is based on...
3 Questions
3 Questions with Eric Bernstein BioPhotonics spoke with Eric Bernstein, M.D., the medical center director at the Main Line Center for Laser Surgery in Ardmore, Pennsylvania, about a recent study on laser treatment of acne scarring published by the American Society for Laser Medicine and Surgery. Results from the study — encompassing the treatment of 13 subjects with an erbium-doped fiber laser — show promise in...
BioOpinion
Photoacoustic Imaging Can Democratize Dermatology Care Light-based technologies have long been used for therapeutics and diagnostics in dermatology. Their applications are wide-ranging and common, such as UV light-based treatments of the skin, vascular lasers to treat abnormal blood vessels, intense pulsed light to treat lesions and unwanted hair, and various imaging methods, such as confocal microscopy to monitor skin conditions. Imaging techniques...

Mosquitoes are feeling the heat in their hunt Is there anything more annoying than a mosquito bite? They’re itchy, scratchy (a whole bevvy of synonyms), and might just leave your skin a bit bloody if you dig your claws into them long enough. If that didn’t make you ponder these airborne menaces enough, then here is a fun fact: Only female mosquitoes bite people, because they need the blood for egg development. It’s enough to make those who...
