A DNA probe that translocates from one anchor site to another by toehold-mediated DNA strand displacement is used to monitor transient molecular encounter events on live cell membranes.
A superconducting quantum interferometer is exploited to fully control the direction of the coherent component of the electronic heat current flowing through a temperature-biased Josephson junction.
Nonmagnetic colloidal nanocrystals demonstrate magnetic properties due to spins of dangling bonds at their surface resulting in formation of dangling-bond magnetic polarons.
Multiple urethane groups in the same rod-like structure template the assembly of aromatic helices to form artificial folded architectures as large as 20 kDa with atomic precision.
The dipole–dipole magnetic interaction between individual atoms on MgO surfaces is quantified by performing electron spin resonance by means of a scanning tunnelling microscope, opening new paths towards structural imaging with sub-nm resolution.
The high output voltage of triboelectric nanogenerators enables well-controlled ion pulses for nanoelectrospray molecular mass spectrometry and surface modification.
A combination of mechanical constraints and directed assembly of silk-fibroin leads to the generation of engineered hierarchical structures with control over multiple length scales from the macro, to the micro and nanoscales.
Ruthenium nanoparticles homogeneously dispersed in a nitrogenated, two-dimensional carbon matrix show high turnover frequency and small overpotential for hydrogen evolution reaction both in acidic and alkaline media.
Nanoscale intracellular electrodes and CMOS integrated circuit technology are combined to realize a new intracellular and network-level all-electrical electrophysiological imager.
Individual particles can be programmed to chemically communicate with their neighbours, giving rise to collective behaviours such as dynamic travelling fronts and spatial pattern creation.
Nanosensor arrays based on single-walled carbon nanotubes can detect protein efflux from single, isolated microorganisms in real time, allowing the dynamics of genetic transfection and influence of reproduction to be measured.
Magnesium silicide nanoparticles can scavenge oxygen in the acidic tumour microenvironment and starve tumours by blocking oxygen and nutrient supply, offering a new avenue for cancer-starvation therapy.
