BIOSENSOR DEVELOPMENT

Current biosensor developments can be summarised by different trends. For traditional enzymatic biosensors such as glucose sensors, steady i mprovements of well known basic principles have been made in order to achieve better sensor stability. On the other hand, new affinity senso rs such as nucleic acid sensors, transmembrane sensors, and sensors ut ilising whole cells or even cell networks have became-of increasing in terest. New ways to miniaturise biosensors and to control their interf aces down to the molecular level have been introduced (the bioelectron ics approach). High-throughput screening based on various signal trans duction principles has become of increasing importance.
