Optical-chemical sensor system: (a) outline of the experimental setup; (b) surface plasmon resonance- plastic optical fiber (SPR-POF) platform covered by a thin molecularly imprinted polymer (MIP) layer; (c) SPR-POF platform covered by a thick MIP layer. The grey block represents the resin support (1 cm × 1 cm × 1 cm) in which the POF is embedded.
