Abstract

The quartz crystal microbalance with dissipation monitoring (QCM-D) technique is a label-free and highly sensitive approach to study binding events at a sensor surface in real-time. QCM-D is based on the piezoelectric effect where the fundamental frequency of the oscillating quartz sensor is dependent on its mass.
Mass binding to the sensor surface thus causes a measurable frequency decrease (Dmp–Df). The QCM-D technique also enables the measurement of the viscoelasticity and spatial distribution of an adlayer on the sensor surface.
