Bacterial backpacks for targeted delivery of piezoelectric nanoparticles to enhance sonodynamic immunotherapy

BMEMat, EarlyView.
Leveraging bacterial hypoxia targeting, KBTO NPs accumulate at the tumor site. Under the ultrasound irradiation, KBTO NPs produce reactive oxygen species to kill tumor cells and eliminate bacteria, preventing overgrowth and inflammation. The lysed bacteria act as antigens to trigger antitumor immunity and further enhanced by the immune checkpoint ...

Channel‐trap coupled charge modulation in sulfur‐vacancy‐rich nanotransducer for enhanced dual‐mode cancer catalytic therapy

BMEMat, EarlyView.
Sulfur vacancy‐rich ZnS–NCx heterojunctions are engineered as dual‐function nanotransducers, in which channel‐trap‐coupled electronic pathways enable efficient capture and transport of ultrasound‐induced piezoelectrons. This vacancy‐mediated regulation simultaneously enhances sonodynamic activity and biomimetic POD/GSHOx catalysis, triggering a self ...
