Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>Molecularly imprinted polymers are being proposed for the development of novel biorecognition elements for active components. In this study, an imprinted chitosan coated silica nanoparticles (I‐CS<italic>@</italic>SiO₂) polymer was prepared by a simple procedure, in which, naringin (NG) with antioxidant activity, acted as a template, silica as a matrix and CS as a functional polymer. The binding properties were discussed by the equilibrium binding experiment method. Experiments show that the adsorption characteristics of I‐CS<italic>@</italic>SiO₂ are better than that of nonimprinted polymer. It exhibited high selectivity for NG when compared with the nonimprinted polymer, with an imprinting factor <italic>α</italic> of 1.74. Scatchard analysis of the I‐CS@SiO₂ indicated that there was a class of binding sites during the I‐CS<italic>@</italic>SiO₂ recognizing NG: The dissociation constant of <italic>K_D</italic> is 0.016 mmol L⁻¹, the maximum apparent binding capacity of <italic>B</italic>_max is 6.56 μmol g⁻¹. © 2014 Wiley Periodicals, Inc.
