Activation of Metal Complexes With Ultrasound Waves for Targeted Anticancer Therapy

Angewandte Chemie International Edition, EarlyView.
Ultrasound enables non‐invasive activation of metal‐based therapeutics deep within tumors. Acoustic cavitation can drive sonodynamic reactive oxygen species generation or mechanochemical metal–ligand bond dissociation, enabling controlled release of bioactive payloads.

The Performance of Quartz Dosimeter with Range to MGy

Journal of Isotopes, 2022
To study the new type of dosimeter with a dose up to the ultra-high dose range of MGy, the electron spin resonance (ESR) method is used to measure the signal intensity of the sample irradiated by gamma rays or electron beams.

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 ...

Observation of Electromagnetically Induced Transparency Within an Electron Spin Resonance Transition

, 2015
A sharp transparency feature is induced in an allowed electron spin resonance (ESR) transition by driving a nominally spin-forbidden transition. The width of the feature is narrower than the homogeneous linewidth of the ESR transition and is interpreted ...

Defect‐engineered tungsten oxide nanowires as redox‐metabolic nanozymes for gut inflammation‐infection syndromes

BMEMat, EarlyView.
Defect‐engineered WO3 nanowires serve as a multifunctional nanozyme platform to treat IBD complicated by Salmonella co‐infection. By integrating catalytic ROS/RNS scavenging and targeted metabolic interference of pathogens via molybdenum substitution, these nanowires effectively resolve intestinal oxidative stress, inhibit infection, and restore ...
