Stable gold graphitic nanocapsule doped hydrogels for efficient photothermal antibacterial applications

Abstract

Herein, we have fabricated gold nanorod graphitic nanocapsule (AuNR@G) doped poly(vinyl alcohol) (PVA)/chitosan (CS) hydrogels, which possessed highly efficient and stable photothermal antibacterial properties for both Gram-negative E. coli and Gram-positive S. aureus under the irradiation of a near-infrared laser.
