Invited Research Lecture on Surface Plasmon Resonance Photonic Biosensors

Date: 01 Feb 2010 - 01 Feb 2010

Venue: Training Room 1 & Room 2, Level 3

Surface Plasmon Resonance (SPR) has been known to be an effective approach for label-free detection of binding between bio-molecular species. Several companies have been very successful in turning SPR into commercial equipment products for the R&D community. With the recent expansion of nanophotonics and bio-related research activities, the research team led by Professor Aaron H P Ho has been exploring new ideas in SPR photonic biosensors. They started the SPR work with the demonstration of a highly sensitive biosensor design based on the measurement of differential phase between the s- and p-polarisation components. Unlike conventional SPR systems in which the SPR data is measured through varying the angle of incidence, the novel phase-sensitive measurement approach does not require any change in angle of incidence. This makes the new technique well suited for imaging applications, which also leads to parallel sensing of multiple analyses. Co-organised by IEEE Photonics Society, this lecture will address several novel ideas on achieving very high resolution in phase detection. The recent research results on Surface Enhanced Raman Spectroscopy (SERS) for gene diagnostics applications will also be presented.

About the Speaker
Professor Aaron H P Ho holds a doctorate in Electrical and Electronic Engineering from the University of Nottingham. He is now professor in the Department of Electronic Engineering, The Chinese University of Hong Kong (CUHK). Starting as a compound semiconductor materials scientist, he began his career with the University of Nottingham and University of Leeds, UK (1989-94) as a research fellow. From 1994 to 1996, he was employed as a Senior Process Engineer in Fibre Optics Components Operation of Hewlett-Packard. He embarked on his academic career with the City University of Hong Kong since 1996 as an Assistant Professor in the Department of Physics and Materials Science. His academic interests have evolved over the years to cover a broad range of topics including nano-sized semiconductor materials for photonic and sensor applications, optical instrumentation, photonic biosensors based on the surface plasmon resonance effect and biophotonics. Professor Ho has published over 200 journal/conference/book chapter articles.

Who Should Attend
Research Scientists, R&D engineers, academic staff and engineering and science students who are involved in the areas of biosensing, optics and plasmonics.
