Living systems employ a common set of building blocks that can self-organize into a multitude of different structures. Now, a model system based on programmed non-reciprocal interactions, which generically emerge in non-equilibrium systems with chemical activity, exhibits self-assembly pathways that feature temporal structures in the form of cyclic motifs.
Although the toxicity of graphene‐based nanomaterials on human health has been extensively studied, their impact on the microbiome remains poorly understood. Using zebrafish as a model, we show that graphene oxide modulates the immune system in a microbiome‐dependent manner through a mechanism mediated by the aryl hydrocarbon receptor. The study suggests an interplay among graphene‐based nanomaterials, microbiome and innate immune system.
Let’s motor through the fog of molecular machine terminology, not only by defining our own words clearly, but by embracing the coexistence of multiple meanings in a rational and structured manner.
A nanoscopically thin gold coating at the optical percolation threshold was fabricated using scalable methods. Despite its extreme thinness, the film absorbs about 30% of the solar radiation while being transparent. The resulting photoinduced heating prevents or mitigates fogging on transparent surfaces.
Carbon dioxide can be removed from the atmosphere by increasing the phytoplankton population in the oceans using nutrients. Life cycle assessment, cost analyses and data from previous studies reveal that engineered nanoparticles could increase the efficiency of this process and that it can be made affordable, viable, and safe for marine ecosystems.
Treatment with polycations was shown to selectively target abdominal fat in mice owing to the negatively charged extracellular matrix in adipose tissue. The polycations can inhibit the storage of lipids in fat cells, causing them to shrink and leading to improved metabolic health in obese mice.
The authors identified the origin of LiH formation and a new method of LiF formation on a lithium metal anode, which is through the anion decomposition on the cathode side followed by crosstalk.
A plasmonic metasurface for full-colour nanopainting simultaneously achieves a chiaroscuro presentation, wide-gamut palette, high saturation and dynamic colour tunability.
Accumulation of visceral fat, linked to adipocyte expansion and overgrowth, is the most detrimental aspect of obesity, and a major cause of obesity comorbidities. We develop a cationic nanomedicine based on polyamidoamine dendrimers that specifically targets visceral fat and shrinks adipocytes, inhibiting diet-induced obesity and improving metabolic health in murine models.
This Analysis considers the potential benefits and challenges of applying engineered nanoparticles for artificial-ocean-fertilization-driven carbon sequestration
An optical signal transduction pathway through feedback-controlled homeostatic temperature oscillations and mechanoresponse enables dynamic functionalities in a hydrogel.
Downregulation of specific proteins named scramblases might enhance tumour immunosuppression. In this paper the authors first show that the scramblase Xrk8 is overexpressed in tumour cells upon treatment with chemotherapeutics, and then develop a nanomedicine platform for co-delivery of a cancer prodrug and an siRNA directed against the Xrk8 gene, showing therapeutic effect and enhanced immune response in animal tumour models.
Lorentz electron ptychography, a coherent diffractive imaging method, unveils magnetization singularities in a skyrmion lattice in FeGe and captures subtle internal structures near the skyrmion cores, boundaries, and dislocations.
By applying strain to artificially reduce the crystal symmetry of a non-centrosymmetric two-dimensional material, a very large bulk photovoltaic effect is uncovered with anisotropic properties that reflect its non-linear origins.
