Functional biosensor systems via surface-nanoengineering of electronic elements

Bioelectronics is a progressing interdisciplinary research field that involves the integration of biomaterials with electronic transducers such as electrodes, field-effect transistors or piezoelectric crystals. Surface engineering of biomaterials such as enzymes, antigen-antibodies or DNA on the electronic supports controls the electrical properties of the biomaterial/transducer interface and enables the electronic transduction of biorecognition events, or biocatalyzed transformation, on the transducers. The development of biosensor systems of tailored sensitivites and specificities represents a major advance in bioelectronics.
