To avoid potential adverse effects, it is relevant to study how nanoparticles interact with their surroundings. Here we present examples of how nanoparticle interaction with a variety of surfaces can be analyzed.
QCM-D is designed to detect minute variations in frequency, f, and dissipation, D. Here we have compiled a checklist that will help you optimize the reproducibility of your QCM-D measurements by minimizing unintentional changes of the recorded parameters.
Lipid-based systems are used in various fields of research, e.g. in the design and development of biosensor platforms, biomaterial coatings and drug delivery applications. In this overview, we present examples of how these lipid-based systems can be characterized using 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.
Proteins tend to passively adsorb to surfaces. The amount adsorbed depends on many factors such as the protein itself, the ambient conditions and the surface material. So how can the adsorbed amount at these various conditions be assessed? Here we show how protein adsorption can be quickly measured.
