It can provide excellent specificity and recognition ability to the target analyte. The polymer material synthesized by the technique is called molecularly imprinted polymers (MIPs). Bovine Serum Albumin (BSA) is a globular protein in bovine serum. Albumin in the blood maintains osmotic pressure, pH buffering, carrier action and nutrition. The aim of this study was to develop a highly selective MIP with high affinity for bovine serum albumin for removing bovine serum albumin from complex serum samples. In this study, bovine serum albumin was selected as a template molecule, and two molecular monomers MAA and 2-VP, and cross-linker EGDMA were used to synthesize molecularly imprinted polymers by means of overall polymerization, and the surface characteristics of molecules were observed by scanning electron microscopy. The synthesis ratio and experimental procedures were then optimized based on the adsorption capacity of the template molecule BSA. The best result was obtained when the ratio of template/functional monomer/cross-linker was 1:16:80 using 2-VP-MIPs (324 μg/mg, IF=2.12) as monomer. This proved that the synthesized MIPs material could successfully remove abundant BSA in protein mixtures.牛血清蛋白分子模印聚合物甲基丙烯酸2–丙烯醯胺基–2–甲基丙磺酸Bovine serum albuminmolecularly imprinted polymermethacrylic acid2-propenylamine-2-methylpropanesulfonic acid學術論文
