Chemically and biologically functionalized piezoelectric sensors are attractive alternatives to surface sensitive
transducers due to their surpassing versatility. The fourth volume of Springer Series on Chemical Sensors and Biosensors includes a comprehensive theoretical treatment and the current state-of-the art applications of the quartz crystal microbalance (QCM). Interface circuits and the study of viscoelasticity and
micromechanics as well as surface roughness with the QCM are discussed. The broad field of
analytical applications of piezoelectric sensors is covered, which ranges from nucleic acid detection, immunosensors, protein-membrane interactions, monitoring of cells by imprinted
