Overview

Manufacturer: Biolin Scientific, Q-Sense E4

QCM is a technique used to analyse surface phenomena such as thin film formation, interactions and reactions. The QCM sensor is sandwiched between a pair of electrodes and is oscillated at its resonance frequency by alternating voltage. Its resonance frequency is dependent on the total mass of the sensor and the layers attached to the sensor. The frequency of the sensor decreases when mass is attached to the sensor. The QCM sensor can be coated with a variety of films to investigate their interactions with molecules in solution. QCM is commonly used to measure the interactions of proteins, polymers, surfactants and cells with surfaces in solution.

Benefits of the Quartz Crystal Microbalance (QCM)

Applications in kinetic studies of self assembly processes, thin film formation, protein and drug interactions; and viscoelastic behaviours of thin films and adsorbed/immobilised layers.
