New light-activated, drug-delivery system for targeting tumours shows promise.
- Nanostructured semiconductors become superabsorbers
Nanoimprinted germanium thin films boast broadband light absorption.
- Graphene makes good VUV photodetector
Vacuum-ultraviolet photovoltaic device might be used to study interstellar objects.
- Engineers reinvent the inductor after two centuries
On-chip devices made from intercalated graphene exploit the mechanism of kinetic inductance.
- Semiconductor nanosensor measures membrane potential
New device might be used to record action potentials from multiple neurons as well as electrical signals on the nanoscale – for example, across just one synapse.
- 2D MXenes make photonic diodes
Researchers have made the first “passive” optical devices from Ti3C2Tx and C60 that allow for one-way transmission of light.
- High-temperature superconductivity gets agile
Observations of superconducting behaviour at 92 K in powders of YBa2Cu3Ox nanotube morphology suggest the possibility of applications that are no longer hampered by the usual brittle properties of cer …
- Mobile nanotweezers move sub-micron particles
The devices, which are based on ferromagnetic helical nanostructures integrated with silver nanoantennas that produce mechanical force in response to light, could find use in applications such as lab- …
