This study reports a fully integrated 128 × 8 optoelectronic memristor array with Si complementary metal–oxide–semiconductor circuits, featuring configurable multi-mode functionality. It demonstrates diversified in-sensor computing tasks and consumes 20 times less energy than GPUs.

The study presents a modular DNA origami-based single-molecule nanosensor that separates sensing from the signal output. It achieves high fluorescence resonance energy transfer contrast and enables tuning of the response window for improved sensor specificity, multiplexing and logic sensing.

Optically addressable spin defects, such as the NV centre in diamond, have enabled the nanoscale measurement of external stimuli. Here, Gao, Vaidya and coauthors observe a single spin colour centres in boron nitride nanotubes, which, due to their spin S = 1/2 ground state, allow for omnidirectional magnetic field sensing. ’

The fabrication of a molecular quantum sensor on the tip of a scanning tunnelling microscope enables the detection of minute magnetic and electric fields of single atoms with sub-angstrom resolution.

Quantum sensing at the atomic scale has proved challenging. Now, a quantum sensor comprising a molecular spin, which can be addressed by electron spin resonance, attached to the tip of a scanning tunnelling microscope enables the measurement of weak electric and magnetic fields with sub-ångstrom spatial resolution.

Superconducting quantum interference devices can accurately measure temperatures even below 1 mK, but there’s more to them — as Thomas Schurig explains.
