Selectivity of molecularly imprinted solid phase extraction for sterol compounds

MIPs (molecularly imprinted polymers) for 17β-estradiol were prepared using 2-(trifluoromethyl) acrylic acid (TFMAA) as functional monomer and trimethylolpropane trimethacrylate (TRIM) as cross-linker by precipitation polymerisation. Data from HPLC system were calculated, and separation properties of several MIPs were reported. MISPEs (molecularly imprinted solid phase extractions) were performed with MIPs as sorbent, and absorption properties...
