This paper explains the results of the research conducted on the QCM biosensor with the AT cut crystal unit as the sensor in experiments carry out in liquid. In the design of the crystal sensor, the strong Energy Trap Effect is applied. A newly developed sensor system that combines both the analog and digital frequency measurement principle is used to measure the short-term stability and the long-term stability. Based on these results together with the application of the Immunoassay method, the antigen-antibody reaction is observed and the dependence of frequency change on antibody concentration is examined. As a result, it is confirmed that the newly developed experiment system and the crystal sensor can be applied to the QCM biosensor.
