Prof. Dr. Huangxian Ju now works at the School of Chemistry and Chemical Engineering in Nanjing University, Nanjing, China as the director of State Key Laboratory of Analytical Chemistry for Life Science. He received B.S., M.S. and Ph.D. degrees from this university in 1986, 1989 and 1992, respectively, and has performed many pioneering studies on nanobiosensing, electrochemical cytosensing, quantum dots-based electrochemiluminescence biosensing, in-situ monitoring of cell surface carbohydrates and in situ quantitation of intracellular functional biomolecules. He is the fellows of the International Society of Electrochemistry, the Royal Society of Chemistry and Chinese Chemical Society. His current research interests are in analytical biochemistry, nanobiosensing, bioimaging and molecular diagnosis, focusing on signal amplification and life analytical chemistry. He has published 898 papers (621 papers in journals with IF>5), 6 English books, 7 Chinese books, 20 chapters and authored 45 patents with more than 43600 citations in SCI journals and an h-index of 103 (GS h-index 114 and >50000 citations), and won the first outstanding achievement award of Chinese chemical sensors in 2019, 2022 Advanced Measurement Science Lecture Award of American Chemical Society, 3 first-class S&T prizes from Jiangsu Province Government, 3 first-class prizes in natural science from Education Ministry of China, 3 first-class S&T prizes from Chinese Association for Instrumental Analysis, 4 second-class and 2 third-class S&T prizes from Jiangsu Province Government.
