A new magneto-optical material consisting of a nanostructured gold film on top of a ferromagnetic dielectric demonstrated significantly enhanced Faraday and Kerr effects.
The cellular uptake of gold nanoparticles is sensitive to the way cells are positioned and the effects of nanoparticle sedimentation on uptake should be considered in future in vitro studies of large and/or heavy nanoparticles.
Composites composed of single-walled carbon nanotubes and titania nanocrystals can be synthesized using a genetically engineered M13 virus as a template, and used to create highly efficient dye-sensitized solar cells.
Silver nanoparticles with thin palladium shells are active and selective catalysts for the production of hydrogen from formic acid at room temperature.
Giant magnetoresistive nanosensors are used to quantify the binding kinetics of proteins at the surface of the sensor array, thus offering a sensitive assay for applications in antibody and drug development, and clinical diagnostics.
Colloidal dispersions of carbon nanotubes in polymers can be used to make electrically conductive composites with percolation thresholds that can be tailored by adding latex particles.
Pregnant mice treated with silica and titanium dioxide nanoparticles show abnormalities in the placenta and have smaller uterine and fetuses than untreated control mice and those receiving larger particles.
Thin films of single-wall carbon nanotube have been used to create stretchable devices that can be incorporated into clothes and used to detect human motions.
Coating the walls of synthetic nanopores with fluid lipids slows down the translocation of proteins, eliminates non-specific binding and prevents clogging, thus offering a way to improve the performance of nanopore-based sensors.
The contact resistance of a junction between graphene and palladium is shown to be strongly affected by carrier transport in graphene underneath the palladium, and is measured to be just two to three times larger than the minimum resistance achievable.
The kinetics of DNA hybridization can be explored by measuring the conductance of a carbon nanotube that has a single strand of DNA covalently attached to a point defect.
