(Received November 24, 2017; Accepted January 4, 2018)

Keywords: directional coupler, silicon nitride waveguide, molecularly imprinted polymer (MIP), human serum albumin (HSA)

A microfabricated directional coupler (DC) was used for the label-free, real-time detection of proteins. As an alternative to biomolecules such as antibodies, molecularly imprinted polymer (MIP) was used. With human serum albumin (HSA) as a model analyte, distinct responses were observed. On the other hand, the sensor did not respond to bovine serum albumin (BSA). Also, with a nonimprinted polymer (NIP), no responses were observed for HSA. The MIP could be regenerated, and responses of the same sensor after three cycles of measurement and regeneration gave similar values.
