Extracellular Vesicles: Classification, Biological Functions, Diseases, and Therapeutic Opportunities

open access: yesMedComm, Volume 7, Issue 10, October 2026.
• EV content maintains cellular homeostasis and is involved in several disease onset and progression. • miRNA export in EVs depends on: RNA‐binding proteins recognizing motif sequences and on epitranscriptomic modifications. • The disclosure of delivery mechanisms is crucial for developing personalized EV‐based therapeutic tools.

Three‐Stage Fluid‐Assisted Dual‐Mode Janus E‐Skin for Thermally Comfortable Multiplexed SERS Sweat Analysis and Strain Monitoring

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Wearable sweat sensors face persistent trade‐offs between multiplexed detection, signal stability, and wearing comfort. Here, we present a Janus electronic skin (e‐skin) with dual‐mode functionality, offering both thermal and moisture comfort.

Development ICP-MS isotope dilution preconcentration techniques for determination of platinum group elements in volcanic rocks [PDF]

open access: yes, 1999
Understanding PGE geochemistry in low abundance (i.e. sub ppb level) geological samples has been hampered by the absence of an accurate, low blank, preconcentration technique. Ni- S fire assay, the traditional preconcentration method, has been critically

From Tetracycline to Sulfamethoxazole: Photocatalytic Degradation and Mechanistic Insights in Aquatic Environments

open access: yesRare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT The pollution caused by antibiotics to aquatic ecosystems is becoming increasingly serious, thus more effective treatment methods are urgently required. Although the photocatalytic degradation behavior of tetracycline (TC) is relatively well understood, sulfamethoxazole (SMZ), an emerging pollutant originating from large‐scale livestock ...

Novel Hg2+-imprinted polymers based on thymine–Hg2+–thymine interaction for highly selective preconcentration of Hg2+ in water samples

open access: yes, 2012
A novel functional monomer T-IPTS, 3-isocyanatopropyltriethoxysilane (IPTS) bearing thymine (T) bases, was synthesized for imprinting Hg2+. Then a novel Hg2+ ionic imprinted polymers (IIPs) based on thymine-Hg2+-thymine (T-Hg2+-T) interactions, i.e.
