In this study, a wound dressing based on PLGA and Aloe vera containing lipid nanoparticles (NLCs) was developed. NLCs were added in order to add a lipid component that could avoid the adhesion of the dressing to the wound and improve its handling. Membranes with and without NLCs were composed of uniform fibers of about 1 µm in diameter. Their porosity was above 80% and their thickness was about 160 µm. Both dressings showed similar water vapour transmission rate 1100 g/m2day. The formulation containing NLCs presented a higher ultimate tensile strength (2.61 ± 0.46 MPa) and a higher water uptake. Both formulations were biocompatible in vitro. Furthermore, the cell adhesion assay demonstrated that both membranes had a low adherence profile, although it was lower with the dressing containing NLCs. Finally, their efficacy was evaluated in a full thickness wound healing assay conducted in db/db mice, where both enhanced healing similarly. Accordingly, the PLGA-AV-NLC membrane might be a promising strategy for the treatment of chronic wounds, since it improved handling in comparison to the formulation without NLCs.
