Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Advancing Fruit Bioimpedance Monitoring With Sustainable, Soft, And Bio‐Based Electrodes Beyond ECG

Advanced Electronic Materials, Volume 12, Issue 18, 21 September 2026.
Electrical impedance spectroscopy enables non‐destructive fruit quality monitoring, but conventional ECG and needle electrodes compromise signal stability, fruit physiology, and sustainability. This perspective highlights the transition toward soft, biocompatible, and biodegradable electrode interfaces based on natural substrates, bio‐derived ...

Biochemical Modulation of Fe2O3/CuFe2O4 Nanocomposite via Two‐Stage Calcination: Antimicrobial Efficacy and In Vivo Toxicological Profiling

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Fe2O3/CuFe2O4 nanocomposites with wide‐spectrum antimicrobial activity were fabricated using a two‐step calcination method. The nanocomposites strongly inhibit both Gram‐positive and Gram‐negative bacteria, suppress biofilm formation, and show antifungal activity.

Threats and Shifts in Microbial Communities of Salars Associated With Direct Lithium Extraction and Brine Reinjection

Global Challenges, Volume 10, Issue 9, September 2026.
Lithium for rechargeable batteries is increasingly extracted from brines in high‐Andean salars. Direct Lithium Extraction (DLE) technologies are promoted as sustainable alternatives to conventional evaporation ponds. This work explores how brine modification and reinjection may affect microbial communities and ecosystem functioning, highlighting the ...

From Plasma Settings to Agricultural Dose: Toward Reporting Standards for Cold Atmospheric Plasma and Plasma‐Activated Water in Agriculture

Plasma Processes and Polymers, Volume 23, Issue 9, September 2026.
Cold atmospheric plasma and plasma‐activated water should be defined by process, chemistry, delivered dose, and biological exposure rather than treatment labels alone. A process‐defined framework integrating reactor conditions, reactive‐state chemistry, aging, target‐normalized dose, and bioresponse improves reproducibility, comparability, scale‐up ...

Antimicrobial properties of hindered amine light stabilizers in polymer coating materials and their mechanism of action

Frontiers in Bioengineering and Biotechnology
UV-stabilizers are a class of additives that provide extended polymer resistance to UV-degradation, but have also been suggested to have antimicrobial activity, potentially preventing the spread of pathogens, and inhibiting microbial-induced ...

Silver and Antimicrobial Polymer Nanocomplexes to Enhance Biocidal Effects

International Journal of Molecular Sciences
Antimicrobial resistance has become a major problem over the years and threatens to remain in the future, at least until a solution is found. Silver nanoparticles (Ag-NPs) and antimicrobial polymers (APs) are known for their antimicrobial properties and can be considered an alternative approach to fighting resistant microorganisms. Hence, the main goal
