Biography

I investigate the implementation of plasmonic optical sensors with novel nanofabrication techniques and their optical performance. I has lots of experience in clean room environment and a variety of fabrication techniques, i.e. photolithography, e-beam lithography. In particular, I engineered nanohole array sensors into three modalities for different application scenarios. At first, I applied a template transfer technique to produce an on-chip nanohole array sensor with improved optical performance. Plasmonic optical fibres were patterned as flexible nanoprobes for real-time biosensing. These novel sensor designs led to my comprehensive research on the control of transfer process via choosing proper media and adjusting their morphology parameters. Furthermore, I established a universal performance analysis model for surface plasmon resonance and deduced the structure-irrelevant sensitivity expression. This model can explain the reasons of many experimental facts such as extra-high sensitivities of some novel plasmonic structures. Most importantly, the analytical results agree well with previous published data from a wide range of research groups. Recently, I broadened the template transfer technique to fabricate large-area freestanding metal nanomembranes, which had not been implemented in any other method before and would serve as plasmonic transducers, substrates and more beyond nanophotonics.
