Abstract

<abstract abstract-type="main"> <title>ABSTRACT</title> <p>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 <italic>in situ</italic> 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 <italic>in situ</italic> frequency measurement, the degradation‐rate constants (K) of BR on imprinted HAP film is about 8.05 × 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 &amp; Sons, Ltd.</p> </abstract>
