title: [Advances in piezoelectric quartz crystal biosensor and its applications].
abstract: Piezoelectric quartz crystal biosensor is a new sensor developed with the comprehensive utilization of the high sensitivity to mass and the surface characteristics of quartz crystal such as density, viscosity, dielectric constant, conductance, and the high specificity of biologic identification molecules. It has the features of high sensitivity, high specificity, simple operation, high analysis speed, low cost, small size, on-line detection, etc. It can be of wide application in the areas of medical laboratory diagnosis, environment monitor, foods sanitary control and industrial production. In this paper, the fundamental principle, structure and its applications are reviewed.
