impedance crystal
2.The adsorption of bovine serum albumin(BSA)onto nanocrystalline hydroxyapatite and TiO_2 was studied by electrochemical quartz crystal impedance and FTIR-ATR spectroscopy. The response parameters of piezoelectric quartz crystal(PQC)resonance,frequency and the changes in the double electric layer capaci- tance were obtained during BSA adsorption.
