Abstract
An adaptive strategy for sensitive detection of chemicals is proved in electrically induced deflections of an optical fiber. The surface of the fiber, close to one end, is modified by a sensing polymer film. Upon contact with solutions, the adsorption of ions onto the polymer changes the surface charge and bends the fiber in an electric field. The concept has been confirmed in several systems including detections of pH and metal ion, nanoparticles, and self-assembled monolayers. The dependence of the sensitivity on the strength of electric field provides an adaptive approach with adjustable sensitivity for chemical sensing.
