Chronic
wounds have become a major health problem worldwide. Curcumin
(Cur), with strong anti-inflammatory and anti-infective properties,
is introduced as a unique molecule for wound dressing applications.
In the present study, Cur-loaded chitosan/poly(ethylene oxide)/collagen
(Cho/PEO/Col) nanofibers were developed for wound dressing applications
by the blend–electrospinning process. Structural, mechanical,
and biological properties of nanofibers were evaluated using SEM,
FTIR, tensile testing, in vitro release study, Alamar blue cytotoxicity
assay, and in vivo study in a rat model. According to the results,
Cur was successfully released up to 3 days without any significant
cytotoxicity of the above hybrid to human dermal fibroblasts. In vivo
studies on full-thickness wounds in the rat model indicated significant
improvement in the mean wound area closure by applying Cur-loaded
Cho/PEO/Col nanofibers. The electrospun Cho/PEO/Col nanofibers loaded
with Cur could be considered as a promising type of wound dressing
in the wound-healing process.
