Magnetite-β-cyclodextrin@poly(ethyleneglycol dimethacrylate-co-methacrylic acid)
core-shell microspheres imprinted with baicalein (
Fe3O4-β-CD@MIPs) were
synthesized by ultrasonic assisted precipitation polymerization (UAPP) using
methacrylic acid (MAA) as functional monomer and EGDMA as crosslinker in
presence of Fe3O4-β-CD nanoparticles as template and baicalein (BAI) as imprinting
molecule. The structure, morphology and magnetic property of the resultant
Fe3O4-β-CD@MIPs have been systematically characterized by the transmission
electron microscopy (TEM), Fourier-transform infrared spectra (FT-IR), vibrating
sample magnetometry (VSM), and thermogravimetric analysis (TGA). The unique
recognition ability of
Fe3O4-β-CD@MIPs for BAI was evaluated by the adsorption
experiments via comparing those of
Fe3O4@MIPs and
Fe3O4-β-CD@NIPs
non-imprinted nanoparticles.
