Synthesis of ruthenium‐based metal ionic liquid polymer microspheres as an artificial enzyme for colorimetric detection of prochloraz residues in strawberries

Abstract

Metal nanomaterial as artificial enzyme has high oxidase-like activity, good stability, and low cost. The ruthenium-based salicylic acid vinyl imidazole ionic liquid is subjected to radical polymerization to obtain ruthenium-based ionic liquid polymer microspheres. The oxidative activity-like artificial enzyme was synthesized by reducing the ruthenium-based ionic liquid polymer microspheres with sodium borohydride. The research shows that the artificial enzyme based on ionic
