CCR2-mediated chemotactic plant-derived extracellular vesicles for targeting and remodeling the immune microenvironment in cerebral ischemia-reperfusion injury treatment

The recruitment of peripheral immune cells into the brain and the subsequent formation of an inflammatory microenvironment are key drivers of cerebral ischemia-reperfusion injury (CIRI). Current nanosystem-based therapeutic strategies primarily target the brain parenchyma, yet of...

In situ real-time determination of SO 2 photochemical oxidation in nanoscale sea salt aerosols based on dark-field microscopy

Abstract. Heterogeneous reaction processes of aerosols play an important role in air quality and climate change. However, the lack of in-situ measurements of single-nanoparticle reactions results in large uncertainties in modeling the nanoparticle reaction kinetics. The study int...

An Optically Transparent Metamaterial Window Based on Metal Meshes With Integrated Absorption and Transmission

ABSTRACT This work presents an absorptive–transmissive integrated metamaterial window using a quartz substrate and micrometer‐scale metallic meshes. The structure employs a three‐layer design comprising a resonant layer, a dielectric spacer, and a frequency‐selective surface. It...
