This volume in the GBF monographs series on biosensors covers recent developments in different types of biological recognition elements such as enzymes, microbes, antibodies, receptors and lipid membranes, as well as a broad range of transducers such as electrodes, optodes, FETs and peizoquartzes. The book is based upon papers presented at an "All-German Biosensor Meeting" held in 1991 (the first in a series since the reunification of Germany) at the Bogensee Centre outside Berlin.
