We developed a transdermal drug delivery system containing tetracycline as a model antibiotic for wound healing application. Our previous in vitro tests proved no cytotoxic effect nor antibacterial activity of the silica nanofiber based matrix. This study was designed to evaluate biocompatibility of our nanofiber-antibiotic system via reconstructed human skin model, and to confirm sustained release of the incorporated active compound. Further characterization showed that both moisture vapor permeability and enhanced hydrophilicity of the modified nanofibers remained consistent after functionalization. The summarized results proved that this drug delivery system is a perspective solution in potential medicated sustained release patch for wound healing.Keywords: Silica dioxide nanofibers, sustained release, wound healing, antibiotic, topical delivery.
