Biosensors enable high resolution detections for digital healthcare applications such as COVID-19 (link). Transferring bio-molecules into the sensing platform is the fundamental challenge to use biosensors for dianosis and drug discovery purposes. In addition, signal recognition for multi-species detection brings difficulties in medical diagnostics, mainly related to non-specific bindings (NSB). Microfluidic technology is one solution to facilitate a meticulous environment to control the interaction between antibodies and antigens. But currently the binding kinetic is understood using an idealised, 1:1 discrete model which is far too simplistic to fully characterize a microfluidic biosensor and to translate into commercial application, which is due to the lack of a fundamental understanding on the binding phenomenon. This project aims to build new guidelines based on multiscale approaches to understand binding kinetics and inform microfluidic technologies for the development of fast and reliable measurement techniques, tackling challenges associated with current technologies (link).
