This work presents a new approach for the development of biosensors using tobacco mosaic virus (TMV) nanotubes or coat proteins (CPs) as enzyme nanocarriers. Sensor chips combining an array of Pt electrodes loaded with glucose oxidase (GOD)-modified TMV nanotubes or CP aggregates were used for amperometric detection of glucose as a model system for the first time. The presence of TMV nanotubes or CPs on the sensor surface allows binding of a high amount of precisely positioned enzymes without substantial loss of their activity, and may also ensure accessibility of their active centers for analyte molecules. Specific and efficient immobilization of streptavidin-conjugated GOD ([SA]-GOD) complexes on biotinylated TMV nanotubes or CPs was achieved via bioaffinity binding. These layouts were tested in parallel with glucose sensors with adsorptively immobilized [SA]-GOD, as well as [SA]-GOD crosslinked with glutardialdehyde, and came out to exhibit superior sensor performance. The achieved results underline a great potential of an integration of virus/biomolecule hybrids with electronic transducers for future applications in biosensorics and biochips.}, language = {en} } @article{BaeckerKowollikSchnitzleretal.2009, author = {B{\"a}cker, Matthias and Kowollik, Silvia and Schnitzler, Thomas and Wang, J. and Poghossian, Arshak and Zang, Werner and Biselli, Manfred and Wagner, P. and Sch{\"o}ning, Michael Josef}, title = {Entwicklung eines festk{\"o}rperbasierten Sensorsystems f{\"u}r die Bioprozessautomatisierung}, series = {9.

Due to the impact of the surface resistance, both types of IDE structures display a non-linear behavior in low-ionic strength solutions. The experimental data were fitted to an electrical equivalent circuit and interpreted taking into account the surface-charge-governed properties. The effect of a charged polyelectrolyte layer electrostatically assembled onto the sensor surface on the surface resistance in solutions with different KCl concentration is studied. In case of the same electrode footprint, 3D-IDEs show a larger cell constant and a higher sensitivity to molecular adsorption than that of planar IDEs. The obtained results demonstrate the potential of 3D-IDEs as a new transducer structure for a direct label-free sensing of charged molecules.}, language = {en} } @article{BaeckerPoghossianAbouzaretal.2010, author = {B{\"a}cker, Matthias and Poghossian, Arshak and Abouzar, Maryam H. and Wenmackers, Sylvia and Janssens, Stoffel D. and Haenen, Ken and Wagner, Patrick and Sch{\"o}ning, Michael Josef}, title = {Capacitive field-effect (bio-)chemical sensors based on nanocrystalline diamond films}, series = {Diamond Electronics and Bioelectronics — Fundamentals to Applications III, edited by P.
