Abstract :
This contribution focuses on the detection of nanoparticles in a liquid environment with functionalized quartz crystal resonators (QCR). Different model particles and substances have been used to investigate the influence of the properties of the particles, including interfacial properties, on the measurement signal. Surface functionalization has been employed to vary the attraction between particles and sensor.
