Tissue-like viscoelasticity

A SEM image of a microelectrode array composed of an alginate matrix and carbon nanomaterial additives. All the components of the microelectrode are viscoelastic, matching the mechanical characteristics of biological tissues and allowing the device to seamlessly conform to the surfaces of the heart and the brain for bioelectronics recording and stimulation.

    Persistent luminescence is a promising bioimaging technique that is not affected by background autofluorescence, but its in vivo application is challenged by the fact that the materials currently available are activated by high-energy light, with emission in the ultraviolet and visible spectral windows. In this paper the authors engineer X-ray activated, lanthanide-based nanoparticles with a tunable emission in the biologically relevant NIR-II spectral region, which allows high-contrast, multimodal in vivo deep-tissue organ imaging.

    Bioelectronic interfacing with living tissues should match the biomechanical properties of biological materials to reduce damage to the tissues. Here, the authors present a fully viscoelastic microelectrode array composed of an alginate matrix and carbon-based nanomaterials encapsulated in a viscoelastic hydrogel for electrical stimulation and signal recording of heart and brain activities in vivo.

    While targeted lipid nanoparticles might allow partial delivery of genetic materials to non-hepatic cells, the selectivity of this approach is still unsatisfying. Here the authors functionalize their lipid nanoparticles with a targeting moiety that recognizes a protein conformation specific to gut-homing leukocytes, inducing gene silencing exclusively in this cellular subset and providing a potential therapeutic strategy for inflammatory bowel disease.

    Measuring the levels of circulating SARS-CoV-2 RNA in plasma might represent a more accurate way to detect lower respiratory tract and extrapulmonary infections, which classical COVID-19 detection assays based on nasopharyngeal swabs might miss. Here, the authors accurately detect SARS-CoV-2 RNA in plasma-circulating extracellular vesicles using a CRISPR–Cas-based strategy that shows promising characteristics for potential clinical application.
