Abstract: To address the clinical urgency of simultaneously monitoring multiple biomarkers in chronic wound infections, this study presents the innovative development of an electrochemical sensor based on a MWCNTs/MXene/PVA composite hydrogel. A dual-channel conductive network is constructed via the electrostatic self-assembly of the two-dimensional material MXene and multi-walled carbon nanotubes (MWCNTs). This strategy not only enhances the charge transfer efficiency but also effectively suppresses the [...]
Our summary: This study presents a novel electrochemical sensor using MWCNTs/MXene/PVA hydrogel for detecting multiple wound infection biomarkers.

Soil Microbial Responses to Starch-g-poly(acrylic acid) Copolymers Addition
Published on 2026-02-02 by Katarzyna Sroka, Pawe? Sroka @MDPI
Abstract: Superabsorbent polymers (SAPs) are materials that can absorb and retain water solutions with a mass of several hundred times greater than their own. This work aimed to synthesise and evaluate the effects of highly absorbent starch phosphate-g-poly(acrylic acid) copolymers on the microbiological activity of soils previously used for agriculture. The biopolymers studied were obtained by thermal and chemical oxidation of starch phosphates and copolymerized with potassium salts of acrylic acid. Basi[...]
