The Principles of QCM-I

The Quartz Crystal Microbalance is a well-established and sensitive technique used to measure the interactions of molecules polymers and biological assemblies with a sensor surface in air or liquid label-free and in real time It is based on the change in resonant frequency of a quartz crystal sensor when it is covered with a thin film or

Can MEMS biosensor monitor water toxicity based on quartz crystal microbalance?
MEMS biosensor for monitoring water toxicity based on quartz crystal microbalance. Biointerphases, 15 (2), 021006. Forinová, M., Pilipenco, A., Víšová, I., Kunčák, J., Lynn, N. S., Yudin, P., & Vaisocherová-Lísalová, H. Biosensor for rapid detection of SARS-CoV-2 in real-world samples.
How does a quartz sensor work?
The quartz crystal is sandwiched between two metal (typically gold) electrodes. Functionalizing the electrode’s surface further enhances frequency change detection through to interactions between the sensor and the targeted material. These sensors are sensitive to high frequencies and can recognize ultrasmall masses.
What is a quartz crystal microbalance?
A quartz crystal microbalance (QCM) is an acoustic transducer that converts mass changes on the sensor surface of an oscillating quartz-crystal resonator into an electronic signal. Content may be subject to copyright. ...
What causes a resonant oscillation in a quartz sensor?
Because quartz is piezoelectric, when a voltage is applied between the two electrodes a shear displacement is caused in the crystal. If the voltage is alternated, a resonant oscillation can be stimulated in the crystal when the wavelength of the shear displacement in the quartz corresponds to twice the thickness of the sensor.
