Abstract: Among various artificial antibodies, epitope imprinted polymer has been paid increasingly attention. To modulate the "adsorption and release" behavior by environment stimuli, N-isopropylacrylamide, was adopted to fabricate the thermoresponsive epitope imprinted sites. The prepared imprinted materials could adsorb 46.6 mg/g of target protein with the imprinting factor of 4.0. The template utilization efficiency could reach as high as 8.21%. More importantly, in the real sample, the materials could controllably capture the target protein from the human plasma at 45 °C and release it at 4 °C, which demonstrated the "on-demand" application potentials of such materials in the biomolecule recognition field
