What is a QCM sensor?
QCM sensors are based on resonance frequency changes on a QCM following mass changes on the probe/transducer surface.
What are some examples of QCM devices?
More advanced QCM devices are now available on the market, for example the QCM–1 Sensor instrument (Sierra Sensors GmbH, Hamburg, Germany) which is a fully automated instrument. This is being used at Cranfield University (England, UK) to develop a range of affinity-based sensors for a range of analytes.
What is the QCM technique?
QCM is a simple technique with high resolution, based on the piezoelectric effect that consists of applying mechanical forces on the surface of a piezoelectric material. This causes the appearance of electrical charges, but the reverse effect also occurs, which corresponds to the mechanical deformation by the application of an electric charge.
What is QCM (quartz crystal microbalance)?
Quartz crystal microbalance (QCM) is a mass sensitive piezoelectric device based on an oscillatory quartz crystal capable of detecting nanogram changes in mass. QCM sensors are based on resonance frequency changes on a QCM following mass changes on the probe/transducer surface.
