Read about how polyelectrolyte multilayer build-up, and the resulting multilayer, can be characterized with QSense QCM-D technology.
Polymer brushes, polyelectrolyte multilayers and hydrogels are typically used to achieve desirable properties. Key parameters influencing these properties are layer conformation and the degree of hydration. Here we show a straightforward way to measure polymer brush swelling and collapse.
The versatility of polyelectrolyte multilayers, PEMs, is high, which makes them interesting for e.g. biomedical applications. The functionality is largely determined by the layer properties, which needs to be understood to be tailored. Here, we show how PEMs can be characterized with QCM-D.
Polymers and polyelectrolytes of various conformations are used in many applications where there is a need to tailor the interfacial properties to promote a certain interaction with the surrounding environment. Here we show how polymer layer crosslinking and collapse can be characterized.
Thanks to the complementary information combinatorial QCM-D and ellipsometry can provide, these two allow one to simultaneously monitor both polymer brush swelling and deswelling behavior, as well as attachment and detachment of protein.
