Simulation‐Guided Tracer Optimization for Magnetic Particle Spectroscopy: Interplay of Core, Shell and Anisotropy Across Physiological‐Range Viscosities for Single‐ and Dual‐Frequency Excitation

Small, EarlyView.
Single‐frequency magnetic particle spectroscopy (MPS) and frequency‐mixing (FM‐)MPS exhibit complementary viscosity‐dependent signal responses of magnetic nanoparticles (MNP). MPS differentiates predominantly blood‐associated viscosities, whereas FM‐MPS shows pronounced discriminability in cellular and tissue‐like viscosity regimes (sensitivity windows)

Diffusion‐Limited Microfluidic Focusing: Oscillatory Electro‐Viscoelastic Migration of Nanoparticles and Extracellular Vesicles

Small, EarlyView.
Oscillatory electro‐viscoelastic migration (Osc‐EVM) achieves focusing of particles as small as 20 nm in a 50 µm × 50 µm channel. The colloidal sample experiences sustained electro‐viscoelastic lift over extended durations, effectively prolonging the channel length to infinity by periodically reversing the flow direction and electric field.

Detection and Inhalation Hazard Assessment of Wear Particles Arising From Abrasion of Market‐relevant Graphene Reinforced Composites

Small, EarlyView.
Abrasion of few‐layer graphene (FLG)–epoxy composites generated respirable particles in which FLG remained fully embedded, as confirmed by correlative HR‑TEM, Raman, and ToF‑SIMS analyses. Advanced lung cell models revealed no cytotoxic or inflammatory responses, and only high‑dose epoxy particles reduced mucociliary clearance.

How We Simulate Nanopores

Small Methods, EarlyView.
Nanopore technology has revolutionized single‐molecule sensing, yet it suffers from an inherent interpretive challenge. Molecular dynamics has emerged as a go‐to method for determining the relationship between the structure of translocating molecules and the nanopore current signals.

Plant‐derived nanovesicles as potential drug delivery systems for topical use: Emerging applications in dermatology and cosmetology

VIEW, EarlyView.
Plant‐derived nanovesicles (PDNVs) are naturally secreted by fruit, vegetables, seeds, leaves and other natural sources. Used as drug delivery systems, they can combine intrinsic therapeutic activity, enhanced skin permeation and cargo‐carrying capacity, suitable for dermatological and cosmetic applications including hydration, antioxidant/anti ...

Space and resource use by American crow Corvus brachyrhynchos in an area endemic for chronic wasting disease

Wildlife Biology, EarlyView.
American crow Corvus brachyrhynchos is a common species throughout North America. Crows play a role in the ecology of multiple diseases and a single laboratory experiment has shown the potential for crows to pass infectious prions, such as those associated with chronic wasting disease (CWD), in their feces after being force‐fed with infected material ...

Peritoneal Fluid‐Derived Small Extracellular Vesicle Proteins as Potential Biomarkers for Endometriosis: A Case–Control Study

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To demonstrate the presence of peritoneal fluid (PF)‐derived small extracellular vesicles (sEVs) in endometriosis and control samples, to characterise their protein content and to define endometriosis‐specific biomarkers within the sEV proteome. Design Case–control experimental study. Setting Academic endometriosis centre.
