Q-Sense QCM-D animation; including introduction, measurement principle and output data possible to obtain with QCM-D. The animation also highlight common application areas and shows the set-up and how the instrument is operated. 4.33 minutes. Q-Sense QCM-D animation, short version; including introduction, measurement principle and output data possible to obtain with QCM-D. The animation also shows three application areas and shows the set-up and how the instrument is operated. 2.51 minutes.
Individual measurement examples: Adsorption of two different proteins to the surface. The animation shows how QCM-D measures changes in mass and structure (rigidity of the different layers) of the layers as they adsorb to the surface. Cell adhesion to two different surfaces measured with QCM-D and with microscopy. The animation show that microscopy alone cannot detect the difference in surface attachment that is detected with QCM-D. Cross linking of a molecular layer induced by an environmental factor (e.g. pH or salt change in the fluid flushed over the sensor). The animation shows how the thickness and structure of the layer is measured when the molecules cross-link and collapse on the sensor. Degradation of a lipid film/stain by for example a detergent, enzyme, or single surfactant. The animation shows how QCM-D can be used to measure desorption rates, swelling, and degradation of films on the sensor. Molecular surface interactions, this example shows how QCM-D is used as a biosensor to measure specificity of binding on a functionalized sensor surface such as a biotinylated surface. Multilayer build up, the thickness and structural changes of each layer are measured as the polyelectrolyte multilayer is growing. Swelling, measuring rigidity, thickness, and water content of a polymer film as it swells due to changes in the surrounding medium.
