Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

Advanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
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.

Mitochondria‐Targeted Nanomotor: H2S‐Driven Cascade Therapy for Hepatocellular Carcinoma

Advanced Materials, EarlyView.
A mitochondrial‐targeted nanomotor integrates photodynamic therapy, mild photothermal therapy, and enzyme dynamic therapy into a self‐amplifying cascade through H2S‐driven metabolic reprogramming. Abstract Despite advances in combination therapies for cancer treatment, most strategies rely on modular‐additive designs that lack dynamic molecular cues to
