Conductive adhesive self-healing nanocomposite hydrogel wound dressing for photothermal therapy of infected full-thickness skin wounds
Abstract
Abstract Bacteria-infected wounds and antibiotics abuse have become significant burdens to patients and medical systems. Thus, designing a non-antibiotic-dependent multifunctional wound dressing for treating bacteria-infected wounds is urgently desired. Herein, a series of conductive self-healing and adhesive nanocomposite hydrogels with a remarkable photothermal antibacterial property based on N-carboxyethyl chitosan (CEC) and benzaldehyde-terminated Pluronic F127/carbon nanotubes (PF127/CNT) were developed, and their great potential as agents for photothermal therapy (PTT) of infected wounds was demonstrated in vivo. The hydrogels exhibited a suitable gelation time, stable mechanical properties, hemostatic properties, high water absorbency, and good biodegradability. After loading the antibiotic moxifloxacin hydrochloride, the hydrogels showed a pH-responsive release profile and good antibacterial activity. The tissue adhesive property of the hydrogels allowed them to have a good hemostatic effect in a mouse liver trauma model, mouse liver incision model, and mouse tale amputation model. The addition of CNTs endowed the hydrogel with in vitro/in vivo photothermal antimicrobial activity and good conductivity. An in vivo experiment in a mouse full-thickness skin wound-infected model indicated that the hydrogels had an excellent treatment effect leading to significantly enhanced wound closure healing, collagen deposition, and angiogenesis. In summary, these conductive photothermal self-healing nanocomposite hydrogels as multifunctional wound dressing exhibit great potential for the treatment of infected wounds.

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.
