ABSTRACT
The main goal of the present project was to design and develop ibuprofen (IBU) and layered double hydroxides-vancomycin (LDH-VAN) nanohybrid loaded bionanocomposite fibrous mats to increase the wound healing rate. Thus, first, LDH-VAN nanohybrid particles was synthesized by in-situ incorporation of VAN into the Mg-Al-LDH interlayers during the co-precipitation of hydroxides. Then, LDH-VAN/IBU/CMC-PEO bionanocomposite fibrous mats were fabricated by electrospinning technique. Test samples were examined XRD, SEM, TEM, TGA, and FTIR. In vitro drug release test was performed in the phosphate buffer solution (pH = 7.4) to prove the efficiency of the fabricated bionanocomposite fibrous mats as a sustained-release carrier for both VAN and IBU. All the fabricated bionanocomposite fibrous mats did not displayed any significant cytotoxicity on NIH/3 T3 fibroblast cells. The wound area in the rats treated with LDH-VAN/IBU/CMC-PEO bionanocomposite fibrous mats was less than other treatment groups. Based on histological analysis, the LDH-VAN/IBU/CMC-PEO bionanocomposite fibrous mats possess a faster wound healing than other nanofibrous mats. Data obtained from the present project indicated that LDH-VAN/IBU/CMC-PEO bionanocomposite fibrous mats could accelerate the wound healing process.
