Talk: Seminar Institut für Allgemeine Physik (IAP), TU Wien; 2002-12-03.

Physical chemosensing and biosensing are methods for obtaining chemical and biochemical information from a fluid or organic material by using primarily physical detection methods. Transduction effects from the mechanical, radiant, magnetic, thermal and electrical energy domains are studied and applied.
Application areas are fluid systems, e.g., a car engine or a crystal growth furnace, and biochips for chemical, biochemical and medical analysis. The miniaturization of the sensor systems is attractive because reduced sample volumes bring profit both in sample costs and in test speed. Opportunities and technologies for
miniaturized devices based on silicon- and glass substrates are discussed.
