Endogenous Fe2+-activated ROS nanoamplifier for esterase-responsive and photoacoustic imaging-monitored therapeutic improvement

Sijin Xiang et al.

Summary: This study developed a PPA nanoamplifier by conjugating ART with PEG-functionalized Pd@Pt nanoplates, which showed specific intratumoral esterase-responsive ART release and enhanced ROS-mediated tumor therapy. The PPA nanoamplifier combined the in situ decomposition of ART's endoperoxide bridges by Fe2+ to superoxide anions and peroxidase-like enzymatic catalysis of endogenous H2O2 by PP to hydroxyl radicals, achieving amplified ROS signals and high-efficiency non-Fenton CDT. Additionally, PPA displayed GSH destruction potential and photoacoustic property for imaging-guided CDT.

Negatively Charged Sulfur Quantum Dots for Treatment of Drug-Resistant Pathogenic Bacterial Infections

Yi Wang et al.

Summary: The study engineered negatively charged sulfur quantum dots (SQDs) as an efficient broad-spectrum antibiotic to kill drug-resistant bacteria in vitro and in vivo. SQDs destroy bacterial membrane systems and affect their metabolism through the intrinsic antibacterial activity of elemental sulfur and catalytic generation of reactive oxygen species. Compared to traditional positively charged materials, SQDs demonstrate better hemocompatibility and lower toxicity.
