AIM: The extensive use of vancomycin has given rise to vancomycin-resistant bacterial strains, such as vancomycin-resistant Enterococci (VRE). We aim to explore potent medical treatments that can inhibit the growth of VRE.

MATERIALS & METHODS: Vancomycin-immobilized gold nanoparticles ([email protected] NPs) with polygonal shapes from one-pot reactions were generated within approximately 7 min.

RESULTS & DISCUSSION: The as-prepared Au NPs exhibit not only antibacterial capability but also photothermal competence. The temperature of the sample solution containing the as-prepared [email protected] NPs can be raised by approximately 15°C under irradiation by a near-infrared laser (λ = 808 nm) within 5 min.

CONCLUSION: The required amount of vancomycin on the as-prepared [email protected] NPs combined with near-infrared irradiation for inhibiting VRE is approximately 16-fold lower than that of free-form vancomycin.
