Biological molecular adsorption on crystal hydroxyapatite (HAp) and amorphous Ca10(PO4)6(OH)2 was investigated using quartz crystal microbalance (QCM) method. The pulsed laser ablation (PLA) was applied to coat both kind films for QCM sensors. A crystal HAp sensor was prepared with thermal treatment during the fabrication process. An amorphous Ca10(PO4)6(OH)2 sensor was prepared without any thermal treatment. Not only crystal HAp but amorphous Ca10(PO4)6(OH)2 showed good adsorptive feature compared with conventional QCM on the market. The result showed that a low temperature deposition of HAp is adaptable to polymer-based materials for medical purposes.
