6’-Sialyllactose conjugated to polyamidoamine dendrimers at a well-defined valency and spacing can circumvent drug resistance and inhibit influenza A viruses.
Two electron spins occupying the outer dots in a linear array of three quantum dots experience a coherent superexchange interaction through the empty middle dot that acts as a quantum mediator.
Nuclear spins in gallium arsenide produce noise at discrete frequencies, which can be notch-filtered efficiently to extend coherence times of electron spin qubits to nearly 1 ms.
Investigation of the electronic structure in few-layer phosphorene reveals optical transitions relevant for technologically important electronic and optoelectronic applications.
Multi-terminal superconducting Josephson junctions are used to induce topologically protected transitions between gapless and gapped states, showing the potential for creating artificial topological materials.
Spatially resolved measurements of the absorption, internal quantum efficiency and photoluminescence quantum yield of InP single nanowire solar cells allow the determination of intrinsic losses and thermodynamic limits of these nanophotonic devices.
Magnetotactic bacteria that respond to oxygen gradients can be used to carry drug payloads deep into the hypoxic regions of tumours, offering a way to improve the therapeutic index of various nanocarriers.
Single-crystal graphene can be grown on a copper foil at a rate of 60 μm s-1 by using an adjacent oxide substrate that continuously supplies oxygen to the surface of the copper catalyst.
Individual ion qubits held in a planar ion trap are optically addressed with scalable nanophotonic waveguides and focusing grating couplers integrated with the trap chip.
Lateral displacement pillar arrays can now be used to separate nanoscale colloids including exosomes, offering new opportunities for on-chip sorting and quantification of biocolloids by size.
