JOEL WILLIAMS, ASSOCIATE EDITOR [email protected]Researchers from Aston University have developed a method to improve the accuracy of blood flow measurements in the feet of patients with Type 2 diabetes. The laser-based technique improves accuracy in detecting minute changes in microcirculation, and it improves on the method of laser Doppler flowmetry (LDF), which is commonly used to check circulation in the feet. LDF gives measurements in the form of blood flow averages — which doesn’t always give the doctor enough information. Changes at the microcirculatory level — involving the smallest blood vessels within...Read full articleRelated content from Photonics MediaArticlesIn-Ear Wearable Measures Blood Flow to the Head Prior to FaintingDigital health company STAT Health has unveiled a 24/7 in-ear wearable that uses optical sensors to measure blood flow to the head to better understand symptoms such as dizziness, brain fog,...BioPhotonics Sep/Oct 2023 IssueOptogenetics Identifies Sugar Regulating Pancreatic CellsAn international team led by Professor Nikolay Ninov at the Center for Regenerative Therapies Dresden, part of Dresden University of Technology, used optogenetics to analyze transparent fish...BioPhotonics Sep/Oct 2024 IssueOptical-Plasmonic SERS Platform Clocks Molecular SystemsAn optical plasmonic tweezer-controlled surface-enhanced Raman spectroscopy (SERS) platform developed by Hong Kong University of Science and Technology (HKUST) enables efficient, high-throughput,...BioPhotonics Mar/Apr 2024 IssueOptoacoustics, AI Monitor Disease in Patients With DiabeticsOne complication of diabetes is microangiopathy, a condition affecting the microvasculature, which affects numerous organs, including the skin.
