Ionic Control of Microstructure and Lubrication in Charged, Physically Cross‐Linked Hydrogels

Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.
Here, charged, physically cross‐linked poly(methacrylamide‐co‐methacrylic acid) hydrogels stabilized by a short‐range attractive, long‐range repulsive potential is investigated. This work uncovers how salt addition alters not only swelling, but also the microstructure and dynamics, near‐surface stiffness and charge, and ultimately, its lubricity. Salts

Straightforward Preparation of Polyurethane‐Based Biomaterials with Dual Antibacterial and Anti‐Adhesive Properties for Long‐Lasting Catheter Applications

Advanced Materials Interfaces, Volume 12, Issue 24, December 22, 2025.
This study presents the elaboration of antibacterial, antiadhesive, and antibiofilm polyurethane by a straightforward process based on the co‐extrusion of 2 wt.% of both antibacterial and antiadhesive copolymer. The material proves to be active even after pre‐exposition to biological media and prevents E. coli biofilm formation without toxicity.

The Role of Porosity in SERS

Advanced Optical Materials, Volume 13, Issue 34, December 2, 2025.
This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Functional Groups‐Driven Molecular Design for Broad‐Spectrum Clusteroluminescence in Scalable Monodisperse Polymer Microspheres

Aggregate, Volume 6, Issue 12, December 2025.
This study developed a scalable strategy for fabricating monodisperse cluster‐luminescent polymer microspheres via functional group engineering. The microspheres exhibit broad emission (400–700 nm) and low fluorescence coefficient of variation (CV < 3%), fulfilling requirements for routine flow cytometer calibration.

Electrostatically‐Driven Collapse of Polyelectrolytes: The Role of the Solvent's Dielectric Constant

Journal of Polymer Science, Volume 63, Issue 20, Page 4207-4218, 15 October 2025.
The structure of polyelectrolytes in solution is studied in media of low and high dielectric permittivity. For high dielectric constant solvents, repulsion between dissociated groups leads to extended conformations. In low dielectric constant solvents, attraction between condensed counterions leads to chain collapse, regardless of solvent quality ...

Study of immobilization of bolaform ions on polymethacrylic acid

BIO Web of Conferences
The study of the interactions of polyelectrolytes with organic ions, in particular bolaform ions, that is, having a mirror conformational chemical structural symmetry with respect to the centre of the molecule and exhibiting physiological activity, is particularly intriguing due to its potential for simulating biological processes and its implications ...
