英文摘要： In this project，we plan to prepare piezoelectric sensors with functional order honeycomb-patterned films including metallic mesoporous nanocomposites, mesoporous TiO2, Metal-organic framework materials, photoic crysrtal, and highly ordered microporous polymer film. A detection system is built for simultaneous determination of the parameters such as surface acoustic impedance, electrochemistry and spectroscopy during the interaction processes between the porous film layers and targets. The information related to the changes in surface mass loading, properties of the porous films, electrochemical and spectral characterization, interface resistance and capacitance is obtained. By combination with the morphology of the porous films, the interaction processes are characterized. A multivariable impedance analysis method is developed for piezoelectric sensors with porous films. The changes in surface mass and viscosity of the porous films are measured. By using surface biochemical functional modification, the interaction processes between cell, medicine, protein, DNA are investigated under the condition of porous films. The relation between function and topology of biomacromolecules is discussed.
