Design of highly sensitive waveguide SPR biosensors

Research Area: Lab-on-a-chip label-free biosensors

Main Researcher: Khai Quang Le

Surface plasmon resonance (SPR) sensors have found extensive application in the analysis of biomolecular interactions and detection of chemical and biological analytes, where they provide benefits of real-time, sensitive and label-free technology.
Waveguide SPR biosensors aim to provide highly integrated, highly sensitive, multichannel and robust sensing devices which have the ability to accommodate multiple sensing elements on a single platform or substrate.
In this work, we aim to explore novel configuration for SPR sensors which allow highly integration and highly sensitivity.
