Prof. Guo Tuan's team in JNU's Institute of Photonics Technology, in cooperation with Prof. Zhou Xiaohong's team in Tsinghua University's School of Environment, has made a breakthrough in the specific recognition of environmental estrogens (EEs) by the plasmonic optical fiber biosensing platform. They have published their findings in Light: Science & Applications (IF:17.782) under the title Ultrasensitive detection of endocrine disruptors via superfine plasmonic spectral combs. The two teams jointly developed an ultra-sensitive tilt grating surface plasma resonance biosensor for rapid screening of environmental estrogen, reducing the detection limit of estrogen binding activity equivalent concentration by orders of magnitude compared with other technology in the same period. They also apply this technology to screening for other endocrine interference effects (androgens, progesterone, thyroid hormone, etc.), which is expected to provide fast, portable, marker-free solutions for a wide range of risk screening for environmental trace contaminants. Zhang Xuejun, a JNU doctoral student, is a co-first author of the article, and Guo Tuan and Zhou Xiaohong are the corresponding authors.
