Application of Ag‐Enriched Nanostructures Through Ga+ Irradiation of Silver Butyrate Films in Surface‐Enhanced Raman Spectroscopy (SERS)

Small Methods, EarlyView.
We report a direct‐writing method for patterning silver‐enriched nanostructures with dual functionality: High electrical conductivity, with a resistivity of 95 µΩ·cm, and strong SERS activity, achieving enhancement factors exceeding 107. This approach enables an easy and cost‐effective alternative for the production of microstructures with applications

Mechanical stiffness orchestrates distinct regulation of MRTFs and YAP/TAZ transcriptional cofactors in hepatocytes

The FEBS Journal, EarlyView.
MRTFs and YAP/TAZ proteins, or mechanosensitive transcriptional cofactors (MRTcoF), regulate common genes associated with cellular contractility and immune cell infiltration. Their differential regulation in response to stiffness is linked to changes in hepatocyte's aspect ratio. MRTFB does not undergo nuclear translocation under these conditions. This

Resolución estructural en 3D de electrocerámicas mediante microscopía Raman confocal [PDF]

, 2013
Las propiedades de los materiales cerámicos son una combinación entre las propiedades intrínsecas, definidas por los granos cristalinos, y las propiedades extrínsecas, como son bordes de grano y fases secundarias.

Synthesis, Characterization, and Optical Properties of Undoped and Te‐Doped W(SxSe(1−x))2 and Core‐Shell WS2@W(SxSe(1−x))2 Nanotubes

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
W(SxSe1−x)2, Te:WSSe, and WS2@WSSe nanotubes were synthesized through controlled precursor composition. The W(SxSe1−x)2 and Te:WSSe nanotubes exhibit small‐diameter (<30 nm), high‐yield, and well‐defined excitonic transitions. Composition tuning via S/Se ratios increases interlayer spacing with higher Se content. The incorporation of Te remains limited

Ultrasmall Platinum Nanoparticles for Radiation‐Enhanced Cancer Therapy

Advanced Functional Materials, Volume 36, Issue 45, 5 June 2026.
This work proposes a nanomedicine‐based strategy to enhance X‐ray radiotherapy for cancer treatment. Ultrasmall Pt‐NPs exhibit catalase‐like activity that may contribute to modulation of the tumor microenvironment and amplify interactions between radiation and biological matter, leading to increased DNA damage.

Copper–Collagen Interactions Regulate the Mechanical and Invasive Properties of Tumor Spheroids

Advanced Healthcare Materials, Volume 15, Issue 22, 12 June 2026.
Ionic copper is investigated as a modulator of tumor spheroid growth and invasiveness in a 3D microfluidic glioblastoma model. Copper exposure alters metabolic activity, cytoskeletal organization, protrusion dynamics, and EMT‐related phenotypes in a dose‐ and timing‐dependent manner, revealing how copper bioavailability shapes tumor aggressiveness ...
