Functionalized Polymer Membranes for Plasmonic Sensing with Enhanced Selectivity

Abstract

We investigate theoretically and experimentally the concept of enhancing the selectivity of chemical, biochemical and biological (nano)plasmonic sensors utilizing multifunctionalized polymer membranes. Membrane nanocompositing is done by lamination and surface/pore immobilization. A separator/filter and an affinity-based adsorption enhancer are integrated into a single multifunctional membrane structure. Functionalized membrane may be transferred across platforms and even used for different types of sensing devices.
