Synthesis of Molecularly Imprinted Polymer via Visible Light Activated RAFT Polymerization in Aqueous Media at Room Temperature for Highly Selective Electrochemical Assay of Glucose

The mild environment where most proteins and antibodies in living systems are prepared has inspired fascination among chemists. Herein, a new, rapid, low-cost, and environment-friendly method is proposed to synthesize molecularly imprinted polymers (MIPs) via visible light activated reversible addition-fragmentation chain transfer polymerization in aqueous media at room temperature for highly selective electrochemical assay of glucose. The MIPs with microsphere morphology, the better hydraulic distribution, large surface area, uniform large pore sizes, and high pore volume exhibit a significant adsorption efficiency compared with nonimprinted polymers for glucose. In addition, the MIP sensor recognizing the glucose significantly exceeds that of the other saccharide analogs, possesses regenerative ability, and presents high sensitivity by applying for the detection of glucose in human urine samples.
