Stimuli-Responsive Polymers as Active Layers for Sensors

Document Type

Book Chapter

Abstract

This chapter describes the latest progress in the field of stimuli-responsive soft materials with special emphasis on stimuli that could be used to design dynamic sensors, such as temperature changes, electromagnetic radiation exposure, magnetic fields, electrical fields, and selective binding of biochemically relevant molecules. It also describes the progress in the growing area of multi-stimuli-responsive polymers. The development of models describing the effect of simultaneous or sequential stimuli on the size, chain stiffness, and solvent compatibility of these macromolecules leads to the development of complex multi-signal processing sensors. The chapter summarizes the latest trends in the use of stimuli-responsive polymers, and discusses the remaining challenges and future directions for the development of stimuli-responsive polymeric materials for smart sensors. Stimuli-responsive hydrogels can be potentially utilized to detect many types of analytes. Ionophore-based sensors are a well-studied class of chemical sensors that can exhibit either electrochemical or optical transduction mechanisms.
