The ability to take up and release water is central for many materials, such as hydrogels, whose function depend on the ability to hydrate and dehydrate. Hydration and swelling are also central when dealing with hygroscopic materials. QCM-D can be used to characterize such swelling phenomenon.
Read about how molecule-surface interaction processes such as adsorption and desorption can be analyzed with QCM-D.
How does QCM-D work? Perhaps you know that a QCM-D sensor is made out of quartz, which is a piezoelectric material. Read about what that means.
Proteins are vital for life and perform a wide range of essential biochemical tasks in all living organisms. It is important that the proteins are correctly folded and functional. However, sometimes the control mechanisms fail and accumulated aggregates transform into protein megastructures.
