Facebook Twitter LinkedIn Email
WASHINGTON, D.C., Aug. 3, 2022 — King’s College London and University College London researchers have developed a miniature, high-speed, photoacoustic endoscope that is small enough to fit inside a 20-gauge medical needle. The needle probe demonstrated the ability to provide functional, molecular, microstructural information about tissue, at subcellular spatial resolution and in real time. It could be used as a forward-viewing endoscopic probe and as tool for guiding minimally invasive surgeries, the developers said. The ultrathin endoscope consists of a multimode fiber for delivering the light for photoacoustic...Read full article
