Abstract Diseases caused by bacterial infections place a significant burden on global public health. Sonodynamic therapy (SDT), as an emerging antibacterial treatment, faces clinical challenges due to the non‐polar nature of most sonosensitizers. To address this, acid‐responsive zinc‐porphyrin‐based sonosensitizer (Zn‐TCPP) is developed via simple thermal reaction, which then coated with phenylboronic acid‐modified hyaluronic acid (B‐HA), fabricate B‐HA@Zn‐TCPP. While in mildly acidic microenvironment mimicking infected wound site, released B‐HA@Zn‐TCPP achieves effective SDT activity. The disruption membrane and levels intracellular reactive oxygen species (ROS) verified that inhibition rate can reach 99% within 5 min, without any development resistance after 15 consecutive generations culture. Additionally, under ultrasound (US) ‐mediated cavitation, exhibits excellent penetration into biofilms, achieving 90.04% bactericidal for bacteria biofilms. In vivo studies further demonstrated effectively accelerate healing wounds 98.65% 9 days. Therefore, novel offers viable strategy overcome limitations traditional sonosensitizers infections.

Abstract Persistent biofilm infections pose a critical health threat with their relentless presence and amplified antibiotic resistance. Traditional antibacterial photodynamic therapy can inhibit bacteria extracellularly but struggles to control formation virulence. Thus, there is an urgent need develop photosensitizers, such as ultra‐small gold nanoclusters (AuNCs), that penetrate biofilms internalize into bacteria. However, AuNCs still face the challenge of insufficient reactive oxygen species (ROS) production limited near‐infrared light absorption. This study develops model indocyanine green (ICG)‐sensitized atomic‐precision size effect. approach achieved absorption while inhibiting radiation transitions, thereby regulating generation ROS. Notably, different‐sized (Au 10 NCs, Au 15 25 NCs) yielded varied ROS types, resulting from different energy level distributions electron transfer rates. ICG‐Au NCs treatment efficacy 99.94% against Staphylococcus aureus in vitro significantly accelerated wound healing vivo. Moreover, this highlights unique role ICG‐AuNCs suppressing quorum sensing, virulence, ABC transporters compared larger counterparts. strategy demonstrates effect paves way for innovative approaches infection control.
