چکیده

A new concept for the development of semiconductor field-effect biosensors by modification of a gate surface with tobacco mosaic virus (TMV) nanotubes, serving as enzyme nanocarrier, is presented. TMV nanotubes enable an immobilization of a high amount of enzymes without substantial loss of their activity, resulting in an enhanced biosensor performance. This approach has been experimentally demonstrated by realizing a capacitive field-effect penicillin biosensor using TMV nanotubes functionalized with the enzyme penicillinase as model system.

Penicillin Detection by Tobacco Mosaic Virus-Assisted Colorimetric Biosensors

The presentation of enzymes on viral scaffolds has beneficial effects such as an increased enzyme loading and a prolonged reusability in comparison to conventional immobilization platforms. Here, we used modified tobacco mosaic virus (TMV) nanorods as enzyme carriers in penicillin G detection for the first time. Penicillinase enzymes were conjugated with streptavidin and coupled to TMV rods by ...

Phonon confinement effects in hybrid virus-inorganic nanotubes for nanoelectronic applications.

Genetically modified viruses have been proposed recently as templates for the assembly of nanometer-scale components of electronic circuits. Here we show that, in addition to their role as nanotemplates, viruses can actually improve the electron transport properties in semiconductor nanotubes grown on them. In the considered hybrid virus-inorganic nanostructures, which consist of silica or sili...

Engineering of the membrane of fibroblast cells with virus-specific antibodies: A novel biosensor tool for virus detection.

A novel concept for the assay of viral antigens is described. The methodological approach is based on a membrane-engineering process involving the electroinsertion of virus-specific antibodies in the membranes of fibroblast cells. As a representative example, Vero fibroblasts were engineered with antibodies against Cucumber mosaic virus (CMV) and used for the construction of an ultra-sensitive ...

The Reversible Inactivation of Tobacco Mosaic Virus by Crystalline Ribonuclease

The reversible inactivation of tobacco mosaic virus by crystalline ribonuclease is reported. Studies on the effect of time of standing on the amount of inactivation, and on the effect of dilution and repeated high speed centrifugation on the recovery of virus activity, and the preparation of an insoluble virus-enzyme complex show that the inactivation is brought about at least in part by a comb...

Elastic modulus of viral nanotubes.

We report an experimental and theoretical study of the radial elasticity of tobacco mosaic virus (TMV) nanotubes. An atomic force microscope tip is used to apply small radial indentations to deform TMV nanotubes. The initial elastic response of TMV nanotubes can be described by finite-element analysis in 5nm indentation depths and Hertz theory in 1.5nm indentation depths. The derived radial You...
