✦ Synopsis

Progress in biosensors has mainly been made by the improvement of the biological components and the implementation of microsystem technologies. Enzymes are still the most appropriate recognition elements because they combine high chemical specificity and inherent biocatalytic signal amplification. A breakthrough has been achieved in the application of membrane-integrated receptor systems for analyte recognition and signal transduction in biosensors. Sensor integration of RNA aptamers has been initiated, and the performance of fully synthetic molecularly imprinted polymers has been improved.
