Ultrasound-Mediated Attenuation of Quorum Sensing and Its Impact on Biofilm Structure

Bacteria use quorum sensing (QS) and biofilm formation as essential adaptation and persistence strategies in harsh settings, which contribute to the development of antibiotic resistance and persistent infections. Through signaling molecules, QS allows bacteria to coordinate group behaviors, and biofilms improve microbial resistance and offer structural protection. A potentially effective physical intervention for interfering with QS signaling and biofilm integrity is ultrasound. The modulation of QS pathways by ultrasound, including signaling molecule degradation and interference with QS receptor binding, is examined in this article. The physical disruption of biofilm structures by ultrasonic via cavitation and shear stress is also investigated. Important discoveries demonstrate how well ultrasound attenuates QS and encourages biofilm disintegration, which in turn increases bacterial sensitivity to antimicrobial drugs. The possible uses of ultrasound in both medical and environmental contexts are discussed, emphasizing its role as a non-invasive, targeted strategy for controlling biofilm-related infections and microbial persistence. Despite its promise, the purpose of this review is to provide a brief background on biofilms, and implants, and advance approach for treatment. Further research is needed to refine ultrasound parameters and optimize its integration with other therapeutic approaches for broader clinical and industrial use.
