Abstract
Mass-sensitive transducers are universally applicable since all absorbed or adsorbed analytes give a response. Preferred devices are QCMs, SAWs and in the last years e.g. FBARS. These transducers can be combined with sensitive and selective coatings. In this way analytes can be detected ranging from sub nm to some μm dimensions. Thus, both molecules and large biological particles are accessible. Favorable coatings can be synthesized by molecular imprinting. Bulk effects are used for molecules whereas surface patterning is preferred for proteins, viruses and cells.
