报告题目：Graphene based materials for bioanalysis
报 告 人：Dr. Alessandra Bonanni
Alessandra Bonanni received her Ph.D. from Universtitat Autonoma de Barcelona (Barcelona, Spain). She then moved to Japan as a Postdoctoral Research Associate at the National Institute for Materials Science in Tsukuba. Currently, she is Senior Lecturer at Nanyang Technological University (NTU), Singapore. Her research interest is focused on the use of novel nanomaterials for the development of electrochemical devices for food analysis and biomedical applications. She has published over 70 peer-reviewed articles and has an h-index of 32.
Graphene and graphene-based materials have attracted considerable attention over recent years due to their excellent electronic, electrochemical, optical, and mechanical properties. The high electron conductivity, together with a fast heterogeneous electron-transfer (HET) rate and a large surface area, make graphene an ideal material for applications in electrochemical devices. This presentation will first review graphene main features, synthetic routes and characterization techniques. After which, an overview on our recent works on the use of graphene as electrochemical platform for food science and point-of-care diagnosis will be given. A novel approach will be also illustrated, whereby graphene oxide nanocolloids are being employed as the electrochemical label and the signal generator for analytical detection.
