HONG KONG, Sept. 15, 2023 — A multispectral, super-low-dose photoacoustic microscopy (SLD-PAM) system developed by City University of Hong Kong (CUHK) achieves significantly higher sensitivity than traditional optical resolution photoacoustic imaging. By providing an exceptionally high level of sensitivity, SLD-PAM could help broaden the use of photoacoustic microscopy in biomedical applications. In the future, it could translate to clinical settings; for example, it could be used for ophthalmic exams where a
