Title:
圧電共振器を使用した流体媒質中でのナノ重量測定のための方法及びデバイス
Document Type and Number:
Japanese Patent JP5532500
Kind Code:
B2
Abstract:
The invention relates to a method, to a device for electronic characterisation, and to a measurement cell and support for monitoring a chemical or physical process with results that can be assessed in terms of the weight variation of a coating deposited on a piezoelectric sensor, exposed to a fluid medium with stable physical properties. The invention uses the deduction of an analytic expression establishing a simple connection between the phase variation of a fixed-frequency signal, which queries the piezoelectric resonator, and the variation in the bulk density of the coating. The invention is suitable for implementations that use piezoelectric resonators for characterising biochemical and electrochemical processes, such as, inter alia: piezoelectric biosensors and immunosensors, process and material characterisation by AC electrogravimetry, detection of dissolved chemical or biological substances.
