Abstract: A molecularly imprinted hydroxyapatite (HAP) thin film was constructed onto the surface of quartz crystal using molecular imprinting and surface sol-gel process. Quartz crystal microbalance technique was employed to in situ investigate the interaction between bilirubin (BR) and HAP film. Compared with non-imprinted HAP film, the molecularly imprinted HAP film not only exhibits a much higher adsorption capacity for BR molecule, but shows an enhanced photocatalytic activity in degrading BR. According to the in situ frequency measurement, the degradation-rate constants (K) of BR on imprinted HAP film is about 8.05 x 10-4 s-1, which is two times higher than that obtained on non-imprinted HAP film. © 2012 Curtin University of Technology and John Wiley & Sons, Ltd
