Intranasal Delivery of Bacterial Extracellular Vesicles Enables RNA Cargo Entry Into the Brain

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
ABSTRACT Extracellular vesicles (EVs) released by bacteria are potent mediators of host–microbe interactions. They modulate immune responses, deliver functional molecules and influence disease progression. However, whether bacterial EVs can access the brain and functionally affect host cells remains unclear.

Wafer‐Scale Deterministic Fabrication of Axis‐Ratio–Engineered Silicon Nanoparticles for On‐Resonance Electric–Magnetic Dipole Interference

Small, Volume 22, Issue 32, 8 June 2026.
Wafer‐scale top‐down fabrication yields silicon nanoparticles with exceptional uniformity (CV 1.7%–2.4%), enabling deterministic axis‐ratio tuning. At AR ≈$\approx$ 2.1, electric–magnetic dipoles overlap on‐resonance, producing near‐Kerker forward scattering (F/B ≈$\approx$ 12.5).
