The electrical stimulation of cells through a cell-supporting conductive scaffold may contribute to new therapeutic solutions for nerve regeneration. In this work, biocompatible Polylactic acid (PLA) fibrous scaffolds incorporating Fe(III)Tosylate (FeTos) were produced by electrospinning a mixture of PLA\/FeTos solutions towards a rotating cylinder, inducing fiber alignment. Fibers were coated with the conductive polymer Poly(3,4 ethylenedioxythiophene) (PEDOT) formed by vapor-phase polymerization of EDOT at 70 \u00b0C for 2 h. Different solvents (ETH, DMF and THF) were used as FeTos solvents to investigate the impact on the scaffold\u2019s conductivity. Scaffold conductivity was estimated to be as high as 1.50 \u00d7 10\u22121 S\/cm when FeTos was dissolved in DMF. In vitro tests were performed to evaluate possible scaffold cytotoxicity, following ISO 10993-5, revealing no cytotoxic effects. Differentiation and growth of cells from the neural cell line SH-SY5Y seeded on the scaffolds were also assessed, with neuritic extensions observed in cells differentiated in neurons with retinoic acid. These extensions tended to follow the preferential alignment of the scaffold fibers.<\/jats:p>","DOI":"10.3390\/polym15194004","type":"journal-article","created":{"date-parts":[[2023,10,6]],"date-time":"2023-10-06T01:07:13Z","timestamp":1696554433000},"page":"4004","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["PEDOT-Coated PLA Fibers Electrospun from Solutions Incorporating Fe(III)Tosylate in Different Solvents by Vapor-Phase Polymerization for Neural Regeneration"],"prefix":"10.3390","volume":"15","author":[{"given":"Laura S.","family":"Pires","sequence":"first","affiliation":[{"name":"Department of Materials Science, NOVA School of Science and Technology, NOVA University Lisbon, Campus de Caparica, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4826-0007","authenticated-orcid":false,"given":"Diogo S.","family":"Melo","sequence":"additional","affiliation":[{"name":"Department of Physics, NOVA School of Science and Technology, NOVA University Lisbon, Campus de Caparica, 2829-516 Caparica, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3996-6545","authenticated-orcid":false,"given":"Jo\u00e3o P.","family":"Borges","sequence":"additional","affiliation":[{"name":"Department of Materials Science, NOVA School of Science and Technology, NOVA University Lisbon, Campus de Caparica, 2829-516 Caparica, Portugal"},{"name":"i3N\/CENIMAT, NOVA School of Science and Technology, NOVA University Lisbon, Campus de Caparica, 2829-516 Caparica, Portugal"}]},{"given":"C\u00e9lia R.","family":"Henriques","sequence":"additional","affiliation":[{"name":"Department of Physics, NOVA School of Science and Technology, NOVA University Lisbon, Campus de Caparica, 2829-516 Caparica, Portugal"},{"name":"i3N\/CENIMAT, NOVA School of Science and Technology, NOVA University Lisbon, Campus de Caparica, 2829-516 Caparica, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"31","DOI":"10.1093\/rb\/rbu017","article-title":"Strategies for regeneration of components of nervous system: Scaffolds, cells and biomolecules","volume":"2","author":"Tian","year":"2015","journal-title":"Regen.
