Description

In this work, we demonstrate a novel dopamine sensor using multimode surface plasmon excitations by irradiating white light source on metallic diffraction gratings/plastic substrates. Since the grating pitch is larger than commonly used diffraction gratings, multiple surface plasmon resonance excitations due to several diffraction orders were observed at same time. Layer-by-layer ultrathin films prepared from iron containing bis (terpyridine) polymer (Fe(II)-BTP) and poly (ethylene dioxythiophene): poly (styrene sulfonate) (PEDOT: PSS) were used as an electrochemical mediator for sensing the dopamine. Large changes in grating coupling surface plasmon dips were obtained upon an injection of the dopamine on the LbL/metallic grating surface.
