A four-level conductance switch can be created by using a scanning tunnelling microscope to remove a hydrogen atom from the central cavity of a porphyrin molecule.
Laser-based imaging can distinguish between semiconducting and metallic nanotubes in vitro and in vivo, offering a way to study the interactions of carbon nanostructures in biological systems without the use of labels.
The golem stories of Jewish history can provide a framework for thinking about some of the ethical questions involved in nanotechnology and nanomedicine, as Chris Toumey explains.
A silicon nanowire field-effect transistor coupled to the interior of a cell by means of a hollow silicon dioxide nanotube can detect changes in the electric potential of the intracellular fluid.
Phase-estimation algorithms applied to single electronic spins in diamond allow weak magnetic fields to be measured with high sensitivity and a large dynamic range.
Phase-estimation algorithms applied to single nitrogen nuclear spins in diamond allow weak magnetic fields to be measured with high sensitivity and a large dynamic range.
A nanowire waveguide attached to an optical fibre can deliver payloads into cells and act as an endoscope capable of imaging single living cells with high spatial resolution.
Spin doublets of holes in nanowires with a germanium core and a silicon shell can be manipulated in fast-gated double quantum dots to create quantum bits with long spin lifetimes.
Nanodiamonds have excellent mechanical and optical properties, high surface areas and tunable surface structures. This article reviews the synthesis of nanodiamonds and their use in a variety of applications including drug delivery, tissue engineering and nanocomposites.
A porphyrin molecule anchored to a silver surface can function as a four-level conductance switch in which a single hydrogen atom in the inner cavity of the molecule is manipulated by electrons from the tip of a scanning tunnelling microscope.
Combining solid-state nanopores and nanowire field-effect transistors allows the translocation of single DNA molecules through the nanopore to be detected with a high intrinsic bandwidth and large-scale integration.
The thermal conductivity of a bundle of boron nanoribbons can be significantly higher than that of a single free-standing ribbon, and can be switched between this enhanced value and that of a single nanoribbon by wetting the interface between the nanoribbons with various solutions.
Hollow DNA-based spacer particles are used in the synthesis of nanoparticle superlattices with well-defined geometries, one of which has never been observed before.
