New Progress in Scientific Research by Tsinghua Shenzhen International Graduate School (SIGS)

SHENZHEN, China, Nov. 18, 2022 /PRNewswire/ — Professors Qionghai Dai (from Tsinghua University) and Haoqian Wang’s (from the Division of Information Science and Technology at Tsinghua Shenzhen International Graduate School) research teams integrated their self-supervised denoising framework with fluorescence microscopes for real-time suppression of photon shot noise. This new technique can reduce the minimum photon flux by more than 10-fold and achieves low-dosage, long-term, high-sensitivity imaging of various biological processes such as calcium activity, cell migration, and neurotransmitter release. Their work provides a new solution to the photon-limited challenge of fluorescence microscopy. The research article entitled “Real-time denoising enables high-sensitivity fluorescence time-lapse imaging beyond the shot-noise limit” was published in the journal Nature Biotechnology (
