Resumo |
Ru(bpy)(3)(2+) electrochemiluminescence (ECL) method and electrocatalysis method were first used to study the ion-gate behavior of supported lipid bilayer membrane (sBLM). We found that sBLM, made of dimethyldioctadecylammonium bromide (a kind of synthetic lipid), showed ion-gate behavior for the permeation of Ru(bpy)(3)(2+) in the presence of perchlorate anion. There existed a threshold concentration (0.1 muM) of perchlorate anion for ion-gate opening. Below the threshold the ion-gate was closed. Above the threshold, the number of opened ion-gate sites increased with the increase of perchlorate anion concentration and leveled off at concentrations higher than 1200 muM. Based on it, a new sensor for perchlorate was developed. Furthermore, the opening and closing of the ion-gate behavior was reversible, which means the sensor can repeatedly be used. |
