Abstract
Controlled generation of reactive oxygen species (ROS) is crucial in various fields. Piezoelectric catalysis is an emerging method, particularly in sonodynamic therapy. However, current piezoelectric ROS catalysts have limitations. This study demonstrates a method to induce polarization of inert poly(tetrafluoroethylene) (PTFE) particles using ultrasound, creating piezoelectric electrets. Ultrasonic irradiation of these electrets generates ROS significantly faster than previously reported catalysts. This simple method offers potential for applications ranging from environmental remediation to biomedical therapy.
