Abstract 

A novel hydrogel photonic crystal (HPC) sensor based on complexation reaction has been prepared to be used for Cu(Ⅱ) determination. Histidine-immobilized HPC was fabricated and its responses to Cu(Ⅱ) were monitored through readable Bragg diffraction shifts by using a fiber optic spectrometer. A functional relationship was found between the red-shift Δλ and the logarithm of Cu(Ⅱ) concentrations (lgc) in range of 10-9~10-5 mol·L-1. Effects of histidine content, pH and ion strength on the response of HPC were examined experimentally. The reversibility and the response time of HPC to Cu(Ⅱ) were also investigated, and the response mechanism of the response process was explored.
