Abstract: Molecular conformation and binding modeling were built by Hyperchem 8.0 computational chemistry package and the optimum molecular conformation was obtained by molecular mechanics optimizer. It was found that there were two types of binding sites for norfloxacin on the molecular imprinted particles (MIPs).One was the hydrogen bonds between oxygen atom of MIPs with the carbonyl group of norfloxacin and the other one was the hydrogen bonds between oxygen atom of MIPs with the hydroxyl group of norfloxacin. Moreover, the energies change of the molecules were1.69 x 10^6 J/mol, 1.80 x 10^6 J/mol and 5.37 x 10^6 J/mol and 2.54 x 10^6 J/mol during the binding process of the norfloxacin (NOR), ciprofloxacin (CIP), bisphenol A (BPA) and tonalide (TON) onto the MIPs, respectively. The result indicated that the MIPs had a good selectivity for NOR and CIP than BPA and TON.
