Cover Story: Hyaluronic acid, curcumin, and usnic acid are separately utilized as effective biological agents in medicine, and materials based on their blending have wider therapeutic effects than individual ones. In this study, for the first time, native hyaluronic acid-based nanofibers containing curcumin and usnic acid were successfully prepared by the electrospinning technique. Additionally, unstable and hydrophobic curcumin and usnic acid were loaded into the hydrophilic hyaluronic acid matrix without utilizing the activating (catalyzing) agents. The investigation of fibers based on pure hyaluronic acid with active pharmaceutical ingredients will lay the groundwork for the development of highly effective wound dressings with transdermal drug delivery.
