Optical biosensors for water quality monitoring

Dr Xiaohong Zhou, Tsinghua University

Abstract

To meet the severe water pollution status, the facile water quality monitoring technologies are highly demanded. The trace contaminants, such as most heavy metal ions, organic micropollutants, and environmental estrogens, pose heavy side effect on human being and environment. In this talk, I will review our past research activities in optical biosensor for quantification of trace contaminants in water environment, including two sets of (waveguide- and fiber-based) optical biosensor platforms, biosensing strategies to enhance the sensitivity, stability and reusability when using biological materials (antibody, functional nucleic acid, and estrogen receptor) for solid surface involved bioassay, as well as the practical applications in environmental supervision.

Biography

Dr. Xiaohong Zhou received her Ph.D. degree in Environmental Engineering from Tsinghua University, China, in 2007. After two years of postdoctoral research, she started her own independent career in the School of Environment at the Tsinghua University in 2009. She is currently an associate professor with research interests in understanding of functional nucleic acid and their application as biosensing, optical biosensors for environmental monitoring, effect-directed analysis of environmental contaminants.Dr. Xiaohong Zhou received her Ph.D. degree in Environmental Engineering from Tsinghua University, China, in 2007.
