Abstract: Core-shell structural molecularly imprinted polymer (Cs-MIP) has been successfully prepared by polymerization of MIP on the silica nanospheres surface. The vinyl groups modified on the surface of silica nanospheres have directed the copolymerization of functional monomers and cross linkers in the presence of template molecule, hydroquinone, onto the silica nanospheres surface. The prepared Cs-MIP exhibited fast binding kinetics because the rebinding sites situated at the surface and approximately to the surface of the outer MIP layer. And the Cs-MIP showed higher recognition capacity to hydroquinone than to analogous compounds, such as catechol and resorcinol. An electrochemical sensor fabricated by modifying Cs-MIP on the glassy carbon electrode surface was employed to detect the concentration of hydroquinone with a linear range from 2.0 x 10(-6) to 1.0 x 10(-4) mol/L
