A neuromorphic camera can localize single fluorescent particles to below 20 nm resolution and evaluate the diffusion trajectory with millisecond temporal precision.
Polymerase-chain-reaction-based methods used in clinic to identify respiratory viral infections cannot simultaneously detect multiple viruses or viral variants. Here nanopore nucleic acid sensing is coupled to programmable ribonuclease to simultaneously identify specific short RNA sequences of multiple viruses, without predetection steps such as sample purification or preamplification.
Electrons in two-dimensional semiconductor moiré materials experience competing magnetic interactions. Magneto-optical measurements of moiré devices with controlled screening of the Coulomb interactions now evidence a Wigner–Mott insulating state with frustrated magnetic interactions.
High-performance all-electrical control is a prerequisite for scalable silicon quantum computing. The switchable interaction between spins and orbital motion of electrons in silicon quantum dots now enables the electrical control of a spin qubit with high fidelity and speed, without the need for integrating a micromagnet.
Metasurfaces can solve Fredholm integral equations of the second kind for free-space radiation at optical wavelengths. To this end, an inverse-designed metagrating is coupled to a semitransparent mirror providing feedback to perform an analogue version of the Neumann series.
Catalyst microenvironment induced by mixed CO/CO2 feeds in an alkaline membrane assembly electrolyser determines the catalytic activity and product selectivity in CO2/CO electrolysis.
Although conventional innate immune stimuli contribute to immune activation, they induce exhausted immune cells, resulting in suboptimal cancer immunotherapy. Now, a kinetically activating nanoadjuvant can dynamically integrate two waves of innate immune stimuli, in terms of the order, duration and time window, which results in effective antitumour immunity without immune cell exhaustion.
Covalent confinement drives symmetry breaking in macromolecular arrangements, giving rise to layered low-symmetry self-assemblies of mesh networks in the sub-10-nm scale.
