2005). Rebinding studies showed that pH, temperature, as well as the initial BSA concentration influenced the adsorption capacity of both MIP and NIP hydrogels. 0, where BSA possesses a net negative charge. Although increased temperature did not favor BSA adsorption, the BSA-MIPed hydrogels exhibited a higher template-binding capability than nonimprinted polymers between 5°C and 40°C. Moreover, the binding capacity was also found to be directly proportional to the concentration of template protein during imprint formation.

2000). Inspired by this idea, Li et al. (2006) developed a surface-imprinted polymer nanowire for protein recognition. The template protein was first immobilized on the pore walls of the nanoporous alumina and then filled with a mixture of AAm and N, N-MBisA. After polymerization in the nanopores, the template and the alumina membrane were subsequently removed by chemical dissolution, leaving behind polymer nanowires with protein-binding cavities situated on the surface (Fig. 8). The binding and competitive rebinding studies demonstrated the enlarged surface area on polymer nanowire results in a high proteinbinding capacity and specificity.

These imprinted membranes introduced specific binding sites into porous membranes without reducing their high permeability and demonstrated remarkably increased affinity to template molecules. Bossi et al. (2001) applied the thin film for the fabrication of protein imprints. They coated the polystyrene surface of microplate wells with a thin polymer layer of poly-APBA and employed various proteins (lactoperoxidase, haemoglobin, 31 32 Macromolecule-Imprinted Polymers horseradish peroxidase, CyC, and microperoxidase), covering a range of protein sizes and isoelectric points.
