    • -4 mg. When the PZT plate is immersed in a 1 ml protein solution with 0.1 mg/ml (the minimum concentration in Fig. 2(a)) and 2 mg/ml, the incubation concentration, the adsorption amount is only 0.4% and 0.02% of the total proteins in solution, respectively. These amounts are below the detection limit of conventional quantitative protein assay methods, such as UV/vis spectroscopy (Perkin-ElmerUV/vis spectrometer user's manual).

    • note
    • Although a DC voltage could potentially be used to reduce protein adsorption, a disadvantage could be interfacial electrochemistry that occurs between the electrode and the solution. By using a high-frequency AC voltage, no electrochemical reaction can occur in the electrode-electrolyte interface. Typically, the voltage scan rate used in an impedance analyzer is 100 V/s; so the time required to conduct a chemical reaction is much longer than the charging time of a PZT by AC voltage.
