Targeted laser therapy synergistically enhances efficacy of antibiotics against multi-drug resistant Staphylococcus aureus and Pseudomonas aeruginosa biofilms

Why this matters, in plain language

Bacteria growing as a film on a surface survive antibiotic doses that would kill the same cells floating freely. This study tested whether gold nanoparticles and pulsed laser light could make those films vulnerable again, and found the combination improved antibiotic effect in the laboratory. A laboratory finding, not a treatment.
