The surface morphology of thin molecularly imprinted polymer films has been studied using atomic force microscopy (AFM). The films were produced byspin coating onto glass substrates and examined as a function of host polymer, imprinting template, casting solvent, spin-coater rotation speed and post-production treatment. It was observed that the gross features of such films are template controlled. The fine structure is determined by parameters such as solvent, spin speed or subsequent treatment. The relationship between these observations, polymer-template interactions and the mechanism of film formation in spin coating is discussed. Copyright (C) 2009 John Wiley & Sons, Ltd.
