We designed and synthesized highly porous alginate and gelatin hydrogels with zinc oxide nanoparticles (AGZNPs) as dressings using sol–gel methods. The presence of functional groups and the surface characteristics of the as-synthesised dressings were analyzed via Fourier transforminfrared (FT-IR) spectroscopy, while their morphology was studied via scanning electron microscopy (SEM). Additionally, the mechanical, inflammatory, and antibacterial properties and biocompatibility of the AGZNPs were evaluated to determine the efficiency of these bandages for wound healing applications. The AGZNPs demonstrated enhanced inflammatory and antibacterial properties. The biocompatibility of the nanocomposites was investigated in noncancerous NIH3T3 human fibroblasts. Furthermore, in-vivo examinations showed that the composition of the synthesized AGZNPs enhanced wound healing and promoted rapid cell construction and growth. Therefore, the AGZNP strategy promotes the future application of these nanoformulation hydrogels for wound bandaging in fracture surgeries. |
