The basic building block of a Hund's metal can be constructed from an iron atom adsorbed on a platinum surface and can be probed with a scanning tunnelling microscope.
The submission of the first 'smart pill' for market approval, combined with progress in the European nanomedicine landscape, illustrates the positive outlook for drug therapy and health monitoring, explains Christian Martin.
Recent theoretical advances are starting to elucidate how natural systems use dissipative self-assembly to build their complex nanomachinery and might point to ways in which the same principles can be exploited to fabricate analogous artificial nanoassemblies.
This Review describes the challenges in functionalization of upconversion nanocrystals for applications in multimodal imaging, cancer therapy, volumetric displays and photonics.
By taking advantage of the thermal gradient that is generated in plasmonic systems and by using an a.c. field, plasmonic tweezers can have a large radius of action and can trap and manipulate single nano-objects.
Suturing of ultrasmall blood vessels is now simplified through the use of a hydrogel that can act as a temporary stent on injection and can be removed through light irradiation.
A plasmonic tweezer combining thermal and electric fields can be used to create fast fluid motion for rapid and accurate positioning of single nanoparticles.
The observation of single-photon emission at room temperature from defects in hexagonal boron nitride sheets opens new opportunities for quantum optics.
Single-photon emission at room temperature can be achieved with hexagonal boron nitride due to electron and hole confinement in vacancy-related defects.
Macromolecular crowding decreases diffusion of mRNA and proteins leading to the formation of heterogeneous environments in gene expression experiments in picolitre droplets.
Arrays of circular nanomagnets are used to solve the problem of perceptual organization in computer vision by exploiting their tendency to minimize the total magnetic energy by coupling to each other.
A molecular positioning device made from DNA origami can adjust the average distance between fluorescent molecules and reactive groups in steps as small as 0.04 nm.
Nanoparticles can absorb most of the incoming light irrespective of incidence angle and polarization and condense it into a monochromatic emission in the presence of a dye.
A monovalent form of an engineered streptavidin can now be tethered to AFM cantilevers, representing a reliable anchoring tool with a well-defined pulling geometry for single-molecule force spectroscopy studies of proteins.
Using metal oxides for both the hole- and electron-transport layers in perovskite solar cells significantly improves their stability compared with devices containing organic transport layers.
