    The utility of wet-tissue adhesives has been impeded by the suboptimal adhesive strength. Here the authors report a composite patch integrated with BP nanosheets that improve the wet-tissue adhesion by enhancing the water absorption and mechanical properties of the patch and demonstrate the uses of the patch in hemostasis, physical-activity monitoring and tumour-recurrence prevention.

    With redox-linked synthetic biology and electrobiofabrication, electronic information can be transmitted in a bidirectional manner between biology and electronics. Here the authors design an electrogenetic platform that allows real time electronic control of biological functions from proteins and gene circuits to cell consortia.

    Minimal invasiveness and robust signal detection are required in neural probes. Here, the authors develop NeuroWeb, an ultra-thin, minimally invasive surface electrode array. In vivo electrophysiological and optogenetic experiments show single-unit activity of neurons with high signal-to-noise ratio.

    Nanoelectrodes for measuring intracellular action potentials suffer from issues with success rate, signal strength and fabrication. Here, the authors report on a scalable technique which creates robust nanocrown electrodes with high success rates by electroporation and demonstrate the advance towards preclinical drug evaluation.

    Bone implants with antibacterial and osteogenic properties are important for clinical applications, but creating both properties simultaneously remains challenging. Here, the authors demonstrate a self-activating implant using a hydroxyapatite and molybdenum disulfide coating which accelerates bone regeneration and at the same time prevents bacterial infection.

    Self-powered implantable devices have the potential to extend device operation, though current energy harvesters are both insufficient and inconvenient. Here the authors report on a commercial coin battery-sized high-performance inertia-driven triboelectric nanogenerator based on body motion and gravity that can be used to charge a lithium-ion battery and integrated into a cardiac pacemaker.

    Halide perovskite has been applied for resistive switching memory devices, but there are challenges remained to achieve practical application. By using high-throughput screening based on first-principles calculations, the authors discover that lead-free dimer-Cs3Sb2I9 meets the requirements, which exhibits switching speed of 20 ns.

    Cable bacteria’ form long multicellular filaments that can transfer electrical currents over centimetre-long distances. Here, Meysman et al. show that the electrical currents run along highly conductive fibres embedded in the cell envelope, and charge transfer is electronic rather than ionic.

    The internet of things technologies relies on the development of sensorimotor systems. Here, Karbalaei Akbari and Zhuiykov show a bioinspired sensorimotor system based on an integration of an artificial optical synapse and a liquid metal actuator, which mimics the expansion and contraction of biological muscles.

    Many cell capture systems exist but the characterisation and controlled release of single cells is a challenge. Here, the authors report on the development of a duel trigger release system using a combination of photo and electro triggers to allow for light based analysis without unwanted release.

    Nanomaterials that form a bioelectronic interface with cells are fascinating tools for controlling cellular behavior. Here, the authors photostimulate single cells with spiky assemblies of semiconducting quinacridone nanocrystals, whose nanoscale needles maximize electronic contact with the cells.

    DNA hybridization of two single-strands to form a double-stranded helix is widely used for genomic identification applications. Here, Vernicket al. record duplex formation of 20-mer oligonucleotide using a single-molecule field-effect transistor, where DNA kinetics is affected by electrostatic bias.

    BioLEDs is an emerging group of light-emitting diodes that use duplex-strand DNA to enhance luminescence intensity. Here, Back et al.show that only the specific binding between a pair of single-strand DNA can trigger the enhancement, which potentially makes BioLEDs an easy platform for DNA recognition.
