Abstract:
PURPOSE: A chemical sensor using mesoporous silica-immobilized azopyridine-based compounds is provided to effectively detect a nerve agent through UV/vis spectrum and color changing. CONSTITUTION: A chemical sensor for detecting a nerve agent contains mesoporous silica nanoparticle-immobilized azopyridine-based compounds. The azopyridine-based compound is denoted by chemical formula 1. The chemical sensor is a disc-shaped pellet form. The chemical sensor is reusable by treating with NaOH and isolating the nerve agent after detecting the nerve agent. A method for manufacturing the chemical sensor comprises: a step of dissolving azopyridine-based compound of chemical formula 4 in toluene; a step of adding mesoporous silica nanoparticles; and a step of stirring under a reflux condition.
Abstract:
PURPOSE: A chemical sensor for detecting cyanide ions is provided to effectively detect cyanide ions by UV/vis spectrum change and color change. CONSTITUTION: A bisindole derivative has selectivity to cyanide ions and has a structure represented by chemical formula 1. A chemical sensor for detecting cyanide ions includes a bisindole derivative which is anchored on a mesoporous silica nanoparticle represented by chemical formula 3. The chemical sensor is manufactured in the shape of a disk pellet. A method for detecting cyanide ions includes the UV/vis spectrum change or color change of the chemical sensor including the bisindole derivative.
