Near-infrared light-controllable on-demand antibiotics release using thermo-sensitive hydrogel-based drug reservoir for combating bacterial infection
Abstract
A near-infrared (NIR) light-triggerable thermo-sensitive hydrogel-based drug reservoir that can realize on-demand antibiotics release and hyperthermia-assisted bacterial inactivation was prepared to combat bacterial infection and promote wound healing. The drug reservoir was fabricated by mixing ciprofloxacin (Cip, a potent antibiotic)-loaded polydopamine (PDA) nanoparticles (NPs) and glycol chitosan (GC) to form an injectable hydrogel (PDA NP-Cip/GC hydrogel, abbreviated as Gel-Cip). On the one hand, the positive charge of GC and the adsorbability of PDA NPs made bacteria be readily trapped on the surface of Gel-Cip. On the other hand, the Gel-Cip exhibited minimal leakage under physiological conditions, but could boost Cip release upon NIR light irradiation. Meanwhile, NIR light irradiation could activate the photothermal PDA NPs, and the generated local hyperthermia induced the destruction of the bacterial integrity, leading to bacterial inactivation in a synergistic way. Moreover, the exceptional bacterial killing activity and outstanding wound healing ability of the system were also verified by the S. aureus-infected mouse skin defect model. Taken together, the light-activatable hydrogel-based platform allows us to release antibiotics more precisely, eliminate bacteria more effectively, and inhibit bacteria-induced infections more persistently, which will advance the development of novel antibacterial agents and strategies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
