Antifouling coatings on SOI microring resonators for bio sensing applications

Methylated dendritic polyglycerol (dPG(OMe)) is proposed as an antifouling coating for the application with silicon on insulator (SOI) bio sensors. Sensors were coated with dPG(OMe). Fibrinogen was used to test the antifouling properties. Using SOI ring resonator sensors for the measurement, a reduction of 87% in the binding of fibrinogen to the silicon surface was shown experimentally.
