Bacterial biofilm elimination using gold nanorod localised surface plasmon resonance generated heat.
Highlights:
A technique for antibiotic replacement using heat for biofilm elimination is proposed.
Gold nanorods exhibit localised surface plasmon resonance upon optical irradiation and when relaxing, absorbed energy is dissipated as heat, which is utilized to kill bacteria.
After 5 minutes of near infrared irradiation an average of 71% of early biofilms were eliminated.
