Charged membranes that exist in and around living cells strongly repel incoming nanometer-sized particles - especially particles with little or no electrical charge.
Quantum magnetometers are able to detect and visualize the tiniest damage in ferromagnetic materials. In aerospace technology or the automotive industry, they can help to significantly increase the resilience and safety of systems and materials.
An electrically tunable graphene-based biosensor amplified by surface acoustic waves detects ultrathin protein, peptide and polymer layers at unprecedented resolution, even down to the single molecule limit.
Researchers propose a novel meta near-eye display incorporating a large-area nanoimprint metalens array, a video-rate rendering algorithm, and a commercial micro-display, with a see-through prototype demonstrated.
