【 摘 要 】

Nowadays the photonic crystal hydrogel materials have shown great promise in the detection of different chemical analytes, including creatinine, glucose, metal ions and so on. In this paper, we developed a novel three-dimensional photonic crystal hydrogel, which was hydrolyzed by sodium hydroxide (NaOH) and immobilized with butyrylcholinesterase (BuChE) by 1-(3-Dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride(EDC). They are demonstrated to be excellent in response to sarin and a limit of detection(LOD) of 1×10-9mg mL-1was achieved.
