Polymer-Based Chemical Sensors

The authors developed an optical sensing device consisting in a micro-sphere made from 60:1 PDMS (60 parts base silicon elastomer to one part polymer curing agent by volume), performing detection measurements based on the morphology-dependent resonances (MDR) shifts of the micro-sphere, analyzing also the influence of curing and poling of polymer micro-spheres used as optical sensors. [22], studying nanocomposite-based quantum resistive vapour sensors (vQRS), developed from the assembly of hybrid copolymers of polyhedral oligomeric silsesquioxane (POSS) and poly(methyl methacrylate) (PMMA) or poly(styrene) (PS) with carbon nanotubes (CNT). [...]several sensor surface modification approaches to enhance sensing performance are reviewed. [...]the recent developments in the simultaneous detection capability of multiple neurotransmitters is presented.
