Molecularly-imprinted photonic crystal for detecting organophosphorus toxicants
Publication date: 2012
The invention discloses a novel sensor, and specifically discloses a molecularly-imprinted photonic crystal (MIPC) which is used for detecting organophosphorus toxicants timely and quickly. The MIPC employs methylphosphonic acid and ethylphosphonic acid as imprinting templates. An intensity of a reflectance spectrum of the corresponding imprinted photonic crystal decreases significantly with the increase of the concentration of a target compound or with the absorption time. The MIPC also shows some practical application values, and shows effects of low detection limit and high sensitivity in detections for the organophosphorus toxicants such as sarin, soman, VX and R-VX prototypes.
