Amyloid fibrils generally display chirality, a feature which has rarely been exploited in the development of therapeutics against amyloid diseases. This study reports, for the first time, the use of mesoscopic chiral silica nanoribbons against the in vivo amyloidogenesis of human islet amyloid polypeptide (IAPP), the peptide whose aggregation is implicated in type 2 diabetes. The thioflavin T assay...
To better couple with commercial cathodes, such as LiCoO2 and LiFePO4, graphite‐based composites containing a small proportion of silicon are recognized as promising anodes for practical application in lithium‐ion batteries (LIBs). However, the prepared Si/C composite still suffers from either rapid capacity fading or the high cost up to now. Here, the facile preparation of hierarchical graphene‐scaffolded...
The enormous increase of Raman signal in the vicinity of metal nanoparticles allows surface‐enhanced Raman spectroscopy (SERS) to be employed for label‐free detection of substances at extremely low concentrations. However, the ultimate potential of label‐free SERS to identify pharmaceutical compounds at low concentrations, especially in relation to biofluid sensing, is far from being fully realized...
The requirement of nontoxic and versatile manufacturing frameworks for biologically relevant applications has imposed significant constraints on the choice of functional materials and the complementary fabrication tools. In this context, silk is actively studied, thanks to its mechanical robustness, biocompatibility, wide availability, aqueous processing conditions, and ease of functionalization....
A major challenge in siRNA vectors is developing approaches that ensure that when administered in vivo, the vectors can target their requisite site of action. This study reports a third type of nanoworm, biomimetic nanoerythrocytes for siRNA delivery, except for filomicelle and nanoworm iron‐oxide particle, which is the first approach that allows for targeted siRNA delivery by a process involving...
In article number 1802953, Tiger H. Tao and co‐workers report a silk‐based water lithography technique. This work introduces a wafer‐scale, all‐water‐based, chemical‐free, biopatterning method that allows for rapid prototyping of biologically functional devices and interfaces in an extremely fast fashion, and importantly, in ambient conditions, on both planar and curved surfaces.
MXenes, a newly intriguing family of 2D materials, have recently attracted considerable attention owing to their excellent properties such as high electrical conductivity and mobility, tunable structure, and termination groups. Here, the Ti3C2Tx MXene is incorporated into the perovskite absorber layer for the first time, which aims for efficiency enhancement. Results show that the termination groups...
Precision medicine has made a significant breakthrough in the past decade. The most representative success is the molecular targeting therapy of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) in non‐small‐cell lung cancer (NSCLC) with oncogenic drivers, approved by the US Food and Drug Administration (FDA) as first‐line therapeutics for substituting chemotherapy. However,...
Significant progress in DNA nanotechnology has accelerated the development of molecular machines with functions like macroscale machines. However, the mobility of DNA self‐assembled nanorobots is still dramatically limited due to challenges with designing and controlling nanoscale systems with many degrees of freedom. Here, an origami‐inspired method to design transformable DNA nanomachines is presented...
In article number 1802709, Jean‐Philippe Pellois, Hong‐Cai Zhou, and co‐workers uncover a series of metal‐organic cages as novel and superior cargo delivery scaffolds that target subcellular compartments, such as the nucleus, cytoplasm, and membrane, within a living cell. Through manipulation of the overall charge and surface affinity of the cages, the “nano‐bio” interactions between several cellular...
Two‐dimensional (2D) transition‐metal dichalcogenide (TMD) monolayers of versatile material library are spotlighted for numerous unexplored research fields. While monolayer TMDs exhibit an efficient excitonic emission, the weak light absorption arising from their low dimensionality limits potential applications. To enhance the light–matter interactions of TMDs, while various plasmonic hybridization...

Perelman and co‐workers report a quantitative label‐free surface‐enhanced Raman spectroscopy (SERS) method for identifying and quantifying drugs at ultralow concentrations. Self‐assembled gold nanoclusters entrap drug molecules and laser light excites the surface plasmon resonance, yielding a large SERS signal from the molecule trapped near the hot spot, allowing...
Diatom frustules are a type of porous silicon dioxide microparticle that has long been used in applications ranging from biomedical sensors to dye‐sensitized solar cells. The favorable material properties, enormous surface area, and enhanced light scattering capacity support the promise of diatom frustules as candidates for next generation biomedical devices and energy applications. In this study,...
The ability to create graphene nanoribbons with atomically sharp edges is important for various graphene applications because these edges significantly influence the overall electronic properties and support unique magnetic edge states. The discovery of graphene self‐folding induced by traveling wave excitation through atomic force microscope scanning under a normal force of less than 15 nN is reported...
Massive volume change of active materials in lithium/sodium ion batteries (LIB/SIB) causes severe structural collapse of electrodes and fast capacity decay of batteries. Here, a coaxial composite of single‐wall carbon nanotube bundle (SWCNTB/SnO2) nanoparticles (NPs)/N‐doped carbon shell (SWCNTB@SnO2@C) is constructed, where SWCNTBs with exceptional elasticity are explored as a self‐adaptive substrate...
Understanding the key factors for successful subcellular compartment targeting for cargo delivery systems is of great interest in a variety of fields such as bionanotechnology, cell biology, and nanotherapies. However, the fundamental basis for intracellular transportation with these systems has thus far rarely been discussed. As a cargo vector, porous coordination cages (PCCs) have great potential...
Precise, quantitative measurements of the thermal properties of human skin can yield insights into thermoregulatory function, hydration, blood perfusion, wound healing, and other parameters of clinical interest. The need for wired power supply systems and data communication hardware limits, however, practical applicability of existing devices designed for measurements of this type. Here, a set of...
Water soluble nanocrystals (NCs) are promising materials in aqueous‐processed solar cells because of their high extinction coefficient, low‐cost, and favorable photoelectric characteristics. However, the power conversion efficiency (PCE) of the present aqueous‐processed NC solar cells is restricted by the short depletion region of the active layer and limited Fermi level offset between NCs and the...
In article number 1801822, Xin Zhang and co‐workers employ a vapor‐liquid‐solid method to incorporate silicon dioxide nanowires on frustules, the exoskeleton structures from diatoms. This process features preferential nanowire growth on frustules, which is thermodynamically analyzed. Compared to the original frustule structures, the frustule‐nanowire composite material's surface area increases over...
