This study demonstrates the use of gold nanostars embedded in Staphylococcus aureus biofilms to measure antibiotic diffusion in real time using surface-enhanced Raman spectroscopy (SERS). The findings reveal that antibiotic transport rates within biofilms are significantly lower than in aqueous environments, highlighting the challenges posed by biofilm matrices in antimicrobial treatment.
Background
Biofilms are a major concern in antimicrobial treatment, as they can protect bacteria from higher drug concentrations, making infections difficult to treat. Approximately 80% of human bacterial infections involve biofilms, which are prevalent in various medical contexts, including implanted devices and chronic wounds. Understanding the dynamics of antibiotic diffusion within biofilms is crucial for developing effective antimicrobial strategies.
