Quantitative Imaging of Water Diffusion in Brain Parenchyma at Cellular Resolution Using Stimulated Raman Scattering Microscopy

open access: yesSmall, Volume 22, Issue 63, 12 November 2026.
A multimodal multiphoton imaging framework enables high‐resolution quantification of water diffusion in brain tissue. By tracking deuterated water via stimulated Raman scattering (SRS) microscopy, this study resolves the microscopic heterogeneity of water diffusion at cellular resolution and determines apparent diffusion coefficients in health and ...

Rapid and Efficient Affinity Isolation of Engineered Extracellular Vesicles Encapsulating Functional Proteins via Internal Twin‐Strep Tetraspanin Tagging

open access: yesSmall, Volume 22, Issue 62, 6 November 2026.
Structure‐guided internal twin‐Strep tagging of the tetraspanins CD63 or CD9 enables rapid and efficient antibody‐free affinity isolation of engineered extracellular vesicles (EVs) using Strep technology while allowing luminal protein loading. The approach removes over 96% of contaminants, separates tagged EVs from coexisting viral particles, and ...

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

open access: yesSmall, Volume 22, Issue 63, 12 November 2026.
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

open access: yesSmall Methods, Volume 10, Issue 21, 9 November 2026.
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.

Bayesian Calibration of Dynamic Models of Earthquake Sequences Using Observations From Past Large Earthquakes

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.
Abstract Physics‐based models of the earthquake cycle could be used for time‐dependent hazard assessment. For such an application, their parameters must be calibrated so that simulated earthquake sequences reproduce the statistics of past earthquakes, including recurrence statistics and magnitudes. This is challenging because the dynamics are described
