摘 要：This study investigates the fabrication of hydroxyapatite(HAP)nano-coating on a gold-quartz crystal sensor used for quartz crystal microbalance with dissipation(QCM-D)measur ement using an electr ophoretic deposition *** morphology and thickness of the HAP coating are examined via scanning electron microscopy and nano-indention *** repeatability is verified via QCM-D *** show that electrophor etic deposition with ultr asonic treatment is feasible and cost-effective for fabricating nano-thick HAP coatings on a QCM-D gold-quartz crystal sensor *** suspension concentration and electric-field str ength influence the compactness of HAP *** exists a non-linear re lationship between HAP coating compactness and the suspension concentration/electric-field *** the HAP suspension concentration is 30 g/and the applied electric-field strength is 150 V/cm,the HAP coating on the QCM-D gold-quartz crystal sensor surface is uniform and compact with a thickness of 35 nm and is tightly bonded to the sensor *** obtained HAP-coated sensor is thus suitable for QCM-D measurement.
