VISITING FELLOW

Biography

Mohamed Bahri received his M.Sc. degree in microelectronics and nanotechnology in 2016 from the University of Sousse, Higher Institute of Applied Sciences and Technology, Tunisia. In 2017 and 2018, he was awarded the Tunisian alternance scholarship twice, along with the DAAD scholarship in 2018, to pursue his research work at the Institute of Analytical Sciences (ISA_Lyon_France) and Technische Universität Chemnitz (Chemnitz_Germany). Then obtained his Ph.D. in optical engineering in 2022 from the University of Chinese Academy of Sciences (UCAS), Chongqing Institute of Green and Intelligent Technology (CIGIT), China. Currently, he is a postdoc fellow at Tsinghua Shenzhen International Graduate School, Shenzhen, China. Recently, he joined CenBRAIN Neurotech Centre of Excellence as a visiting scholar to carry out experimental tasks associated with MEMS fabrication and characterization.

Research Interests and Project 

Mohamed Bahri's research area focuses on 2D materials synthesis and adoption for biosensing and biomedical applications. He achieved results on electrochemical monitoring of TNF-α and DNA target based on Si3N4 substrate and Laser Induced Graphene electrode in human saliva and buffer solution, respectively. In addition, he has experience in MEMS microfabrication, though he developed various DNA biosensing platforms based on FET system made of CVD grown graphene and Tungsten Disulfide within an extremely low LOD down to attomoles concentration. During his postdoctoral, his project revolves around the development of a high-performance micro-biosensor for a rapid, stable, and trustworthy sensing platform for specific and ultrasensitive detection of lung cancer biomarkers based on the GFET. With such an anticipated biosensing tool, decisions and classifying patients to whom healthy and bearing lung cancer disease will be easily made at an early stage, which could considerably improve the survival rates.
