Abstract
A novel light-assisted quartz crystal microbalance and a measurement method thereof. The microbalance comprises a QCM/QCM-D chip, an oscillation circuit, a frequency counter, a computer, a reaction chamber, and a light source. Light emitted from the light source is able to irradiate a surface of the QCM/QCM-D chip. By additionally configuring a light source with the ability to irradiate a chip surface, when irradiated the surface of the QCM/QCM-D chip changes properties thereof, and irradiation of the surface of the QCM/QCM-D chip greatly increases the resonance frequency. Correspondingly, irradiation of the surface of the chip also changes mechanical properties and piezioelectric characteristics of quartz crystal, thereby effectively improving measurement sensitivity of a quartz crystal microbalance apparatus system.
