Neuromorphic photodetectors are typically volatile and/or complex with multiple gates, leading to reduced energy efficiency for intelligent perception applications. Two-terminal MoS2 photodetectors have now been developed in which electrically driving the migration of sulfur vacancies enables dynamic modulation of the Schottky barriers and the realization of reconfigurable and non-volatile responsivities.
Integration of diverse techniques for in-plane electrokinetic control of a functionalized gold nanowire’s position and orientation enables applications in nanoscale manipulation, nano-assembly, and single-cell biochemical sensing.
A Berry curvature dipole can be generated at certain symmetry-mismatched van der Waals hetero-interfaces even though each material has no Berry curvature dipole in its band structure.
Intercellular calcium waves (ICW) are mechanosensitive signalling phenomena that coordinate cellular responses in key physiological processes. The force applied by light-activated molecular machines is shown to remotely stimulate ICW. The ICW induced by these molecular machines can be exploited to regulate downstream functions, such as muscle contraction, in vitro and in vivo.
Certain proteins have been optimized over millennia to exhibit shock-absorbing capabilities. To harness these capabilities, synthetic biology was used to incorporate the mechanosensitive protein talin into a hydrogel. The resulting talin shock-absorbing material (TSAM) retains the mechanical properties of talin and can absorb the impact of, as well as capture, supersonic projectiles.
Solution-processed, environmentally-benign quantum dots are able to emit stable streams of very pure single-photons with an optical coherence time reaching 250 picoseconds.
Magnetic domain walls can modulate spin-wave transport in perpendicularly magnetized channels, while magnon spin current can drive domain wall motion in the bi-doped yttrium iron garnet channel device.
This Review discusses the latest theoretical progress related to exceptional points in non-Hermitian physics and the associated implications for emerging technologies in nanophotonics.
In a simple two-probe device made of van der Waals dichalcogenide nano-flakes, two pathways are found to switch ferro-rotational domain states by application of a volt-scale voltage.
This Review highlights the role of transition metal dichalcogenides, hexagonal boron nitride and stacked heterostructures in applications in quantum communication, computation, sensing and single-photon detection.
Discovery of a novel axis through which multi-walled carbon nanotubes (MWCNTs) elicit toxicity in human macrophages, involving the propagation of inflammatory signalling via the Siglec-14-DAP12-Syk pathway, and how it may be controlled pharmacologically.
An automated system that couples microfluidics with plasmonic hot electron injection to accelerate colorimetric detection of DNA and RNA amplification is shown to achieve 95% detection accuracy in human saliva samples. This technique uses different amplification assays for pathogen identification and can differentiate between viral variants and subtypes.
