In addition, MEs showed increased anti-inflammatory activity, reduced irritation, and improved the stability of EOs in previous studies [10][11]. Thus, from an innovative perspective
  • characterizing nanostructured systems such as MEs, including droplet size, optical properties, and rheological profile. M7-EOCF therefore underwent tests to investigate these parameters. First, the M7-EOCF sample was analyzed by dynamic light scattering, which showed that the system had an average hydrodynamic

Graphical Abstract
  • ]. Nanofibers are considered promising materials because of their size and structure, making them suitable for drug delivery, tissue engineering, tissue scaffolding, and other biomedical applications [12]. They exhibit distinct chemical and physical properties that distinguish them from macroscale structures
  • electrospun polymer fibers is affected by electric field intensity, solution viscosity, charge density of the solution, and solution supply rate [56]. The size of the fibers also affects the performance of electrospun nanofiber composites [57]. Numerous polymers and precursors including polylactic acid, PU

These membranes can be tailored with a diverse range of fibers, weights, densities, porosities, pore size distributions, chemical compositions, morphologies, hardness levels, and elastic properties [65][66]. Importantly, electrospun membranes and the ECM share substantial structural and
