QCM-I is a powerful technique for measuring the adsorption or binding of polymers, proteins, nano-particles and other molecules to a surface. Multi-parametric data is obtained in real time, detailing changes of the hydrated mass and rigidity of layers coupled to the sensor surface.
The electrostatically driven adsorption of polymer and nano-particle multilayers is a well-established method for the physical and chemical transformation of surfaces to produce highly tailored and often “smart”, environmentally sensitive interfaces.
Combining QCM-I and OWLS Measurements to Understand Polymer Multilayer Deposition Processes using OWLS and Quartz Crystal Microbalance with Impedance (QCM-I).
An experiment using a quartz-crystal microbalance (QCM) with impedance (QCM-I) is a unique technique popular in characterizing biological films that are structurally complex.
Tracking Biofilms Using an Electrochemical Quartz Crystal Microbalance Introduction Biofilms are microbes attached to a surface. The microbes form a film on the surface, giving rise to the name biofilm. This Application Note deals specifically with bacterial biofilms that convert chemicals to electrical current on electrodes
