A new non-van der Waals 2D material hematene, exfoliated from natural iron ore hematite, shows ferromagnetic ordering and enhanced photocatalytic activity.
Using a nanofabricated array platform to precisely control ligand organization at the single-molecule level, the authors illuminate the role of geometry in T cell receptor signalling.
An adapted framework based on the Ashby material selection strategy can be used to select nanomaterials based on their functional performance and on their environmental and human health considerations.
A new quasi-non-volatile 2D semi-floating gate memory with high speed and long refresh time could bridge the gap between volatile and non-volatile memory technologies.
A non-invasive, transdermal monitor extracts and detects glucose from the interstitial fluid through individual, privileged, follicular pathways in the skin accessible via a miniaturized, graphene-supported pixel array.
Exposure to nanoparticles induces indirect autophagy-mediated signalling events, leading to neuron damage via astrocytes in a human model of the placenta and to DNA damage in the neonatal hippocampus in vivo.
A detailed mechanistic study between nanoparticles and radionuclides reveals the roles of β particles and γ radiation in observed light and the possibility of generating X-rays, expanding the radionuclides available for biomedical applications and offering a multicolour nuclear imaging modality.
The spin state of a single electron is shown to control the transmission of single photons through a nanophotonic waveguide, thus realizing a spin-based photonic switch.
Left-handed amyloid fibrils form nematic and right-handed cholesteric tactoids with confinement-induced transitions from an ordered to an ordered state.
Nanoporous carbon composite membranes exhibit 100% salt rejection and high water flux due to the interfacial sieving effect and the fast transport of vapour in carbon pores, respectively.
The wireless and photoelectrochemical stimulation of primary rat dorsal root ganglion neurons is demonstrated by shining laser light onto coaxially doped silicon nanowires deposited on the neuronal membrane.
