However, the limited predictive power and physiological relevance of conventional in vitro models, combined with the absence of standardized protocols for assessing NP toxicity, remain a major challenge. To address these limitations, the development of skin\u2010on\u2010chip (SoC) systems provides a more physiologically relevant solution, surpassing the constraints of static skin cultures. Here, a novel SoC model with dynamic perfusion and a modular architecture suitable for epidermis\u2010only (EoC) and full\u2010thickness (FT) skin models isdeveloped. Under dynamic conditions, both models are metabolically active, exhibit enhanced barrier function, and display a morphology resembling native human skin. Exposure to titanium dioxide (TiO\n                    <jats:sub>2<\/jats:sub>\n                    ) NPs led to a 32.4% decrease in barrier integrity, a 12.1% reduction in metabolic activity, a 2.9% increase in permeability, and histological evidence of tissue damage. These alterations are associated with an early moderate inflammatory response, as indicated by the upregulation of chemokines. Collectively, these findings demonstrate that the microfluidic device functions as a versatile toxicological tool, with the biological complexity of the FT SoC enhancing its sensitivity for nanotoxicology studies.\n                  <\/jats:p>","DOI":"10.1002\/adhm.202502518","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T07:53:09Z","timestamp":1762156389000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Novel Microfluidic System for 3D Epidermis and Full\u2010Thickness Skin Growth for Nanoparticle Safety Assessment"],"prefix":"10.1002","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7167-653X","authenticated-orcid":false,"given":"Samantha","family":"Costa","sequence":"first","affiliation":[{"name":"BiotechHealth PhD Candidate Institute for Biomedical Sciences Abel Salazar of the University of Porto (ICBAS\u2010UP)  Porto 4050\u2010313 Portugal"}]},{"given":"Ana B.","family":"Carneiro","sequence":"additional","affiliation":[{"name":"Master in Biophysics and Bionanosystems School of Sciences of the University of Minho (ECUM)  Braga 4710\u2010057 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3146-269X","authenticated-orcid":false,"given":"Filipa","family":"Lebre","sequence":"additional","affiliation":[{"name":"International Iberian Nanotechnology Laboratory (INL)  Braga 4715\u2010330 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6685-6969","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Meneses","sequence":"additional","affiliation":[{"name":"Department of Bioengineering Technologies Faculty of Science and Technology TechMedCentre University of Twente  Enschede 7522 NB The Netherlands"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8969-3752","authenticated-orcid":false,"given":"Alar","family":"Ainla","sequence":"additional","affiliation":[{"name":"International Iberian Nanotechnology Laboratory (INL)  Braga 4715\u2010330 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4220-0230","authenticated-orcid":false,"given":"Cacilda","family":"Moura","sequence":"additional","affiliation":[{"name":"Physics Center of Minho and Porto Universities (CF\u2010UM\u2010UP)  Braga 4710\u2010057 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1132-7992","authenticated-orcid":false,"given":"Ernesto","family":"Alfaro\u2010Moreno","sequence":"additional","affiliation":[{"name":"International Iberian Nanotechnology Laboratory (INL)  Braga 4715\u2010330 Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1349-9595","authenticated-orcid":false,"given":"Ana R.","family":"Ribeiro","sequence":"additional","affiliation":[{"name":"International Iberian Nanotechnology Laboratory (INL)  Braga 4715\u2010330 Portugal"}]}],"member":"311","published-online":{"date-parts":[[2025,11,2]]},"reference":[{"key":"e_1_2_9_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tibtech.2023.05.009"},{"key":"e_1_2_9_2_1","first-page":"390","volume":"12","author":"Kanitakis J.
