Inflammation-responsive nanocapsules for the dual-release of antibacterial drugs.

Herein, we design inflammation-responsive nanocapsules containing two antibiotics. The releases are programmed to be triggered under conditions occurring at the different stages of wound healing. The nanocapsules exhibit excellent antibacterial activities against Gram-positive, Gram-negative, and antibiotic-resistant bacteria. Incorporation of small amounts of nanocapsules in hydrogels leads to efficient antibacterial wound dressings.
