Semiconducting polymer nanoparticles can act as light-sensitive interfaces with retinal neurons, and on microinjection in the eye, rescue vision in retinas affected by photoreceptor degeneration, offering a potential new treatment option for inherited retinal dystrophies and late-stage age-related macular degeneration.
Formation of interlayer excitons with high oscillator strength in a WS2/HfS2 heterostructure enables the realization of high-responsivity room-temperature mid- and long-wavelength infrared photodetectors.
The accidental band-crossing origin of Weyl nodes paired with the absence of sizeable band gaps hampers the exploitation of low-energy relativistic quasiparticles in Weyl semimetals. In a gate-tunable high-quality tellurene film, quantum Hall measurements unveil a topologically non-trivial π Berry phase caused by unconventional Weyl nodes in these tellurium two-dimensional sheets.
DNA origami allows the precise spatial patterning of antigens to investigate the impact of antigen spacing and arrangement on B-cell activation in vitro, which is important for the design of efficient vaccination strategies.
Iron sulfide nanoclusters enable on-demand and local generation of nitric oxide, an important lipophilic messenger in the brain, allowing the modulation and investigation of nitric oxide-triggered neural signalling events.
The electronic conductivity of graphene-based porous electrodes can be modulated by their ionic charging state in supercapacitors, enabling a new in operando technique to probe the charging dynamics of electrical double layers under nanoconfinement.
While in 3D materials melting is a single, first-order phase transition, in 2D systems, it can also proceed via an intermediate phase. For a skyrmion lattice in Cu2OSeO3, magnetic field variations can tune this quasiparticle 2D solid into a skyrmion liquid via an intermediate hexatic phase with short-range translational and quasi-long-range orientational order.
Nanoparticles that access lymphatic vessels and are functionalized with degradable linkers, whose half-lives can be programmed, enable the controlled release of therapeutic cargo in different regions of the lymph nodes, allowing the targeting of otherwise difficult-to-reach lymphocyte subpopulations.
A zwitterionic micelle platform enables the oral delivery and high bioavailability of insulin by transporting the protein across mucus and epithelial barriers in the gut without opening tight junctions.
A DNA molecular computation platform allows the rapid diagnosis of lung cancer with high accuracy by analysing specific miRNA levels in clinical serum samples.
Lattice reconstruction in twisted transition metal dichalcogenides manifest in intrinsic asymmetry of electronic wavefunctions for 3R homo-bilayers and strong piezoelectric textures in 2H homo-bilayers.
A distance-dependent two-way magnetic resonance tuning platform combined with dual-contrast enhanced subtraction imaging enables quantitative sensing and imaging in deep tissues with minimal background noise.
Poly(methyl methacrylate) nanocomposites embedding CsPbBr3 perovskite nanocrystals can be used to simultaneously achieve optimized parameters in scintillator devices.
Experimental realizations of magnetic skyrmions, particle-like spin swirls with topological protection, so far have required inversion symmetry breaking or a geometrically frustrated lattice. In centrosymmetric GdRu2Si2, in which a geometrically frustrated lattice is absent, a skyrmion lattice phase emerges, which is probably stabilized by four-spin interactions mediated by itinerant electrons in the presence of easy-axis anisotropy.
Magneto-optical interaction of light with magnetic metasurfaces can give rise to the photonic spin Hall effect such that the light trajectory depends on the polarization of the light. For disordered systems, the probability distribution of the spin-dependent trajectories is a sensitive tool to detect random nanoscale variations in the metasurface.
A multimodal imaging approach using a high-density lipoprotein-derived nanotracer with a perfluoro-crown ether payload enables myeloid cell dynamics to be studied in vivo in mouse models of atherosclerosis and myocardial infarction.
A new method to form Bose–Einstein condensates of quasiparticles based on the rapid decrease in the phonon temperature was proposed and shown experimentally.
