Chitosan/Polyacrylic Acid Functionalized Side-Polish Polymer Optical Fiber-Based SPR Sensor for Cu<sup>2+</sup> Ion Detection
A polymer optical fiber SPR sensor for detecting Cu<sup>2+</sup> ion concentration in water is proposed. The sensor employs a simple side-polish structure and realizes the detection of Cu<sup>2+</sup> ion concentration by employing the chitosan (CS)/polyacrylic acid (PAA) bil...
