“…Protein molecularly imprinted polymers (MIPs) are functionally polymeric materials that specifically recognize template proteins [1,2]. Thus far, MIPs have shown wide application prospects in many fields, such as chemical bionic sensors [3,4], protein separation [5][6][7], natural antibody simulation [8][9][10], and drug sustained release [11,12]. However, the protein bio-macromolecules of the corresponding MIPs are disadvantaged by weak specificity of the functional groups, large size, Article Related Abbreviations: IF, Imprinting factor; LCST, lower critical solution temperature; MCS, modified chitosan; MIPs, Protein molecularly imprinted polymers; NIPAM, N-isopropylacrylamide; NIPs, Non-imprinted polymer microspheres; Q, Adsorption amount (mg/g); SBMA, sulfobetaine methacrylate; β, selection factor.…”
