Journal of Materials Chemistry B, Год журнала: 2025, Номер 13(10), С. 3420 - 3436

Опубликована: Янв. 1, 2025

A piezoelectric nanozyme is a novel biomaterial with the integration of piezoelectricity and activity that has capability killing bacteria promoting cell responses under mechanical stimulus exhibits great prospects in tissue regeneration. Herein, bismuth sulfide (BS) cationic vacancies (VBS) was synthesized, which enhanced activities compared BS. Moreover, hydrogel VBS phenylboronic acid grafted sodium alginate-arginine (VBS-PSA) prepared. Triggered by ultrasound (US) high power (>0.5 W cm-2), VBS-PSA produces large amount reactive oxygen species (ROS) through both piezoelectricity-enhanced sonodynamic efficiency peroxidase-like (POD-like) activity, thereby displaying powerful antibacterial capability. However, low-power US (≤0.5 effect generates electrical signals significantly stimulate osteoblast (proliferation differentiation) enhance catalase-like (CAT-like) for scavengers ROS generation oxygen, creating favorable microenvironment growth. Our study presents strategy to apply hydrogels enhancing synergistically kill responses. The would have potential repair infected bone defects.
