Creating magnetic ionic liquid-molecularly imprinted polymers for selective extraction of lysozyme.

ABSTRACT: A novel magnetic (Fe₃O₄) surface molecularly imprinted polymer (MIP) based on ionic liquid (IL) (Fe₃O₄@VTEO@IL-MIPs) was prepared for the selective extraction of lysozyme (Lys). As the functional monomer of the MIPs, an imidazolium-based IL with vinyl groups was prepared. It can provide multiple interactions with template molecules. The amount of IL was optimized (200 mg). Fourier transform infrared spectrometry (FT-IR), transmission electron microscopy (TEM), dynamic light scattering (DLS), thermogravimetric analysis (TGA) and a vibrating sample magnetometer (VSM) were used to characterize the MIP. The results indicate the successful formation of an imprinting polymer layer. The concentration of Lys in the supernatant was determined by UV-vis sp
