Oncolytic Probiotics with Molecular Pili for Solid Tumor Therapy

Advanced Science, EarlyView.
This study identifies Lactobacillus rhamnosus as an intrinsic oncolytic agent that triggers tumor metabolic collapse via calcium‐dependent ROS bursts. By chemically anchoring collagen‐targeting “molecular pili” to the bacterial surface, the engineered non‐transgenic probiotic (LR@MP) achieves targeted colonization and potent solid tumor suppression ...

Biomimetic Organic Nanozyme as Tumor Vaccines for Targeted Suppression of Ammonia‐Induced T Lymphocyte Death to Augment Breast Cancer Immunotherapy

Advanced Science, EarlyView.
The organic nanozyme IR‐IHpd, which has NIR‐PDT and POD‐like activity, is designed for continuous ROS generation. It is co‐encapsulated with CB‐839 and coated with DC membranes to simultaneously target tumors and T cells. Under NIR irradiation, immunogenic cell death is activated. Concurrently, CB‐839 suppresses ammonia‐induced T lymphocyte death (AITD)

Iron Oxide Nanozyme as Reactive Oxygen and Nitrogen Species Scavenger to Regulate Microglial Homeostasis in Stroke

Advanced Science, EarlyView.
6 nm iron oxide nanoparticles (IONP6) exhibit enzyme‐like activities that scavenge reactive oxygen and nitrogen species (RONS), including nitric oxide (NO). In stroke models, IONP6 promotes microglial polarization toward the M2 phenotype, reduces neuroinflammation, and improves neurological outcomes, offering a promising drug‐free approach to mitigate ...

NIR Light‐Driven Photocatalytic Antibacterial Hydrogels for Synergistic MRSA Biofilm Eradication and Wound Regeneration

Advanced Science, EarlyView.
The nanohybrid hydrogel (Fe‐BOS@C/H Gel) is composed of Fe‐Bi2O2‐XS (Fe‐BOS) photocatalysts and CS‐ADH/OHA (C/H) hydrogel. Fe‐BOS photocatalysts achieve near‐infrared (NIR) light‐driven antibacterial photocatalytic/mild photothermal therapy (APCT/MPTT), effectively eliminating methicillin‐resistant Staphylococcus aureus (MRSA) biofilms. The degradation
