Molecularly Imprinted Colloidal Array for Detection of Explosives
摘要
Abstract
The molecularly imprinted colloidal microspheres with good monodispersity were prepared by using trinitrotoluene (TNT) as template, and acrylamide as monomer and polymerizing by emulsion polymerization. The colloidal microspheres were self-assembled into array by vertical deposition method on a quartz slide, and then molecularly-imprinted colloidal array (MICA) which had opal structure was peeled off and immobilized on glue tape. In this research, the influence of different detection environments on optical response of MICA was discussed, as well as the specific adsorption capacity in response of the optimum testing environment. The results showed that the response of TNT at the concentration of 20 mmol/L in methanol-aqueous (7:3, V/V) solution reached a redshift of 24 nm, which was 1. 4 times of non-molecularly-imprinted colloidal array and 23 times of its analogues. MICA simplified the preparation process of photonic crystals sensor, and represented a noval highly selective, real-time "naked-eye" detection method for explosive.关键词
