4.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.
5.Conclusion Piezoelectric quartz crystal sensor method for determination of the plasma thrombin time is simple, rapid, specific, accurate, cheap, and it might be a valuable method for detection of TT in clinical laboratory.
6.A gold electrode of quartz crystal resonator was modified with mercapto - terminatedβ-cyclodextrin derivative(β-CDd)by self-assembly. The inclusion reactions of naphthalene derivatives withβ-CDd were moniˉtored in situ by using piezoelectric quartz crystal sensor. The influences of temperature,concentration,the number of substituting groups and their positions on naphthalene ring on the stability constant of the inclusion complexes(K in )were investigated.
