In this study, for the first time, native hyaluronic acid-based fibers containing curcumin and usnic acid with an average diameter of 298 nm were successfully prepared by the electrospinning technique and characterized. Additionally, unstable and hydrophobic curcumin and usnic acid were loaded into the hydrophilic hyaluronic acid matrix without utilizing the activating (catalyzing) agents, resulting in the formation of an electrospinnable solution. Only the binary mixture deionized water\u2014dimethyl sulfoxide (50:50)\u2014was used as solvent. The presence of small amounts of dimethyl sulfoxide in the fibrous materials was expected to provide the materials with local anesthetic and antiseptic activity. The effect of electric voltage on the electrospinning process, diameter, and morphology of hyaluronic acid\/curcumin\/usnic acid fibers was investigated in detail. The impact of curcumin and usnic acid on the stability of fiber formation was observed. The investigation of fibers based on pure hyaluronic acid without additional polymers and with active pharmaceutical ingredients will lay the groundwork for the development of highly effective wound dressings and new drug delivery scaffolds.<\/jats:p>","DOI":"10.3390\/ma13163476","type":"journal-article","created":{"date-parts":[[2020,8,7]],"date-time":"2020-08-07T09:30:54Z","timestamp":1596792654000},"page":"3476","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Curcumin\/Usnic Acid-Loaded Electrospun Nanofibers Based on Hyaluronic Acid"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9949-5709","authenticated-orcid":false,"given":"Petr","family":"Snetkov","sequence":"first","affiliation":[{"name":"Institute BioEngineering, ITMO University, Kronverkskiy prospekt, 49A, 197101 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Svetlana","family":"Morozkina","sequence":"additional","affiliation":[{"name":"Institute BioEngineering, ITMO University, Kronverkskiy prospekt, 49A, 197101 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6894-1224","authenticated-orcid":false,"given":"Roman","family":"Olekhnovich","sequence":"additional","affiliation":[{"name":"Institute BioEngineering, ITMO University, Kronverkskiy prospekt, 49A, 197101 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thi Hong Nhung","family":"Vu","sequence":"additional","affiliation":[{"name":"Institute BioEngineering, ITMO University, Kronverkskiy prospekt, 49A, 197101 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"Tyanutova","sequence":"additional","affiliation":[{"name":"Institute BioEngineering, ITMO University, Kronverkskiy prospekt, 49A, 197101 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mayya","family":"Uspenskaya","sequence":"additional","affiliation":[{"name":"Institute BioEngineering, ITMO University, Kronverkskiy prospekt, 49A, 197101 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"101","DOI":"10.1016\/j.eurpolymj.2018.09.003","article-title":"Hyaluronic acid\/Na-alginate films as topical bioactive wound dressings","volume":"109","author":"Okeil","year":"2018","journal-title":"Eur.
