Highly sensitive protein characterisation on a new label-free biosensor system is reported. The system consists of a VCSEL, a plastic guided mode resonant filter and two pin detectors. It is suitable for measuring both static and dynamic interaction among proteins and can detect an antigen concentration as low as 1 pg/ml (6.7 femtoMolar).
