Being essential in biofunctionalization and biocompatibility, the interaction of proteins with surfaces is crucial in many areas of life sciences. Q-Sense’s QCM-D is now routinely used by labs to:
Monitor adsorption and desorption kinetics in real time
Verify the specificity of interactions
Measure the thickness and hydration of protein films
Characterize the affinity between a surface-bound receptor and a soluble ligand
Provide information about the nature and the morphological state of the adsorbed species
Employ various types of surfaces - metals, polymers, functionalized and even nano-structured coatings.
Avoid drying or labelling artefacts, since the measurements are performed label-free and in situ
