Similar to certain enzymes, vanadium pentoxide nanowires show antibacterial activity and can prevent the colonization of marine microorganisms on surfaces such as ship hulls.
Small numbers of arsenic atoms are implanted into a silicon transistor, and the Anderson–Mott transition is observed by controlling the spacing between these dopants.
Using an approach that is analogous to Millikan's oil drop experiment, the size and charge of single nanoscale objects in solution can be directly measured by analysing their thermal motion in an array of electrostatic fluidic traps on a chip.
Iron oxide nanoparticles encapsulated inside a ferritin protein shell can be used to target and visualize tumours without the use of any targeting ligands or contrast agents.
Circularly polarized light has been used to confine charge carriers in single-layer molybdenum disulphide entirely to a single energy-band valley, representing full valley polarization.
Metal nanocubes grafted with polymers can self-assemble into arrays of one-dimensional strings that have well-defined interparticle orientations and tunable electromagnetic properties.
Mixing copper sulphate with phosphate-buffered saline that contains enzymes results in hybrid nanoflowers that display increased enzymatic activity compared with free enzymes.
A biochip fabricated on a silicon dioxide support grid allows genes to express proteins in the absence of cells, and the assembly of these proteins to be imaged in situ using transmission electron microscopy.
Six rhesus macaques injected with a cadmium-based quantum-dot formulation survived without any evidence of toxicity, but cadmium remained in certain organs after 90 days.
A phototransistor in which electric charges are absorbed by colloidal quantum dots and circulated in graphene exhibits high values for gain, responsivity and specific detectivity.
Quantum-dot-based infrared light-emitting diodes can achieve levels of brightness and efficiency that are competitive with state-of-the-art epitaxial devices by using linker molecules to control the distance between adjacent quantum dots.
