Mycobacterium smegmatis porin A (MspA) modified with nitrilotriacetic acid achieves direct and simultaneous discrimination of rare-earth elements, suggesting the potential use of nanopore sensing in geological exploration.
A graphene-nanopocket-protected pure Pt nanocatalyst has been reported for heavy-duty-vehicle fuel cells that deliver high power density, high efficiency and exceptional durability with >200,000-h projected lifetime.
Carbon–hydrogen and carbon–deuterium bonding in organic polymers were mapped in real space with single-nanometre spatial resolution using a monochromated transmission electron microscope.
Single-stranded RNA origami tiles transcribed and folded inside giant liposomes generate micrometre-long filaments that deform the membrane, showcasing the potential of RNA nanotechnology in building functional synthetic cells for mimicking the function of cytoskeletal proteins.
A zeolite-confined Cu single-atom cluster was developed for the electrochemical CO reduction application, which can achieve stable CO-to-acetate conversion at an industrial current density of 1 A cm−2 at 2.7 V with a high acetate Faraday efficiency for over 1,000 h at atmospheric pressure.
In an interferometer using the ballistic propagation of electrons in a quantum Hall conductor, the phase of a single-electron wavefunction can act as a sensor for the detection of fast electric fields of small amplitude.
This study introduces RNA origami nanotubes as self-assembling cytoskeleton mimics for synthetic cells. Expressed in vesicles from DNA templates, these RNA structures reach micrometre lengths, deform membranes and exhibit different phenotypes.
In the layered magnetic semiconductor CrSBr, excitons can strongly couple to nonlinear magnons. This coupling enables tunable magnon frequency mixing, parametric amplification and excitons dressed with up to 20 harmonics of magnons.
A high-entropy nanosurface is engineered for selective glycerol electro-oxidation to a high-value-added glycerate at an industrial current density, demonstrating the effectiveness of tailoring catalytic sites by the construction of high-entropy surfaces for electrochemical catalysis.
Tumour endothelial cell macropinocytosis is the dominant mechanism for nanoparticle entry into the tumour. Enhanced nanoparticle tumour accumulation may be due to upregulated macropinocytosis membrane ruffling compared with most healthy tissues.
In a gate defined quantum dot in Bernal bilayer graphene, a combination of spin and valley protection diminishes spin relaxation drastically and yields a lifetime of 38 seconds.
A transistor made from bilayer A-type antiferromagnet CrPS4 provides control over the spin polarization at the Fermi level and magnetoelectric readout.
Networking remote superconducting quantum computers requires low-noise microwave-to-optical photon conversion. A transducer based on an integrated silicon electro-optomechanical resonator now achieves below one photon of added noise referred to the transducer input while operating continuously under laser drive.
Double-gate transistors of bilayer layered antiferromagnet CrPS4 give full control of the spin polarization of the conduction band and of the magnetization of the accumulated electrons.
Insulin crystals coated with a thin, porous membrane with electrical potential-sensitive channels — named i-crystal — show glucose- and ketone-responsive insulin release. Owing to their high drug-loading content and slow, zero-order insulin release kinetics, i-crystal can regulate the blood glucose level for more than 1 month in mice models with type 1 diabetes.
This article presents a polymeric membrane-enclosed insulin crystal equipped with physiological signal-sensing microdomains, dubbed ‘smart drug crystals’, that enables long-term, glucose- and β-hydroxybutyrate-dually responsive drug release for type 1 diabetes therapy.
Nano-groove traps at grain triple junctions significantly affect cation homogeneity in formamidinium–caesium perovskite films. Shallowing these traps improves interfacial properties and enhances solar cell performance.
Delivering therapeutics to the brain is challenging because of the hard-to-cross blood–brain barrier. Here, the authors show that HER3, which is expressed on the surface of many metastatic tumours, is associated with the brain endothelium and can drive accumulation of HER3-targeted nanoparticles within the brain, for therapy against HER3-positive tumours.
