Bacteria frequently form biofilm communities responsible for numerous persistent infections resistant to conventional antibiotics. Herein, novel nanoparticles (NPs) loaded with the natural bactericide farnesol (FSL NPs) are generated using high-intensity ultrasound. The nanoformulation of farnesol improved its antibacterial properties and demonstrated complete eradication of Staphylococcus aureus within less than 3 h, without inducing resistance development, and was able to 100% inhibit the establishment of a drug-resistant S. aureus biofilm. These antibiotic-free nano-antimicrobials also reduced the mature biofilm at a very low concentration of the active agent. In addition to the outstanding antibacterial properties, the engineered nano-entities demonstrated strong antiviral properties and inhibited the spike proteins of SARS-CoV-2 by up to 83%. The novel FSL NPs did not cause skin tissue irritation and did not induce the secretion of anti-inflammatory cytokines in a 3D skin tissue model. These results support the potential of these bio-based nano-actives to replace the existing antibiotics and they may be used for the development of topical pharmaceutic products for controlling microbial skin infections, without inducing resistance development.<\/jats:p>","DOI":"10.3390\/ijms23147527","type":"journal-article","created":{"date-parts":[[2022,7,7]],"date-time":"2022-07-07T22:11:47Z","timestamp":1657231907000},"page":"7527","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["Antibacterial, Antibiofilm, and Antiviral Farnesol-Containing Nanoparticles Prevent Staphylococcus aureus from Drug Resistance Development"],"prefix":"10.3390","volume":"23","author":[{"given":"Aleksandra","family":"Ivanova","sequence":"first","affiliation":[{"name":"Group of Molecular and Industrial Biotechnology, Chemical Engineering, Universitat Polit\u00e9cnica de Catalunya, 08222 Terrassa, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristina","family":"Ivanova","sequence":"additional","affiliation":[{"name":"Group of Molecular and Industrial Biotechnology, Chemical Engineering, Universitat Polit\u00e9cnica de Catalunya, 08222 Terrassa, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luisa","family":"Fiandra","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, Research Center POLARIA, Universita degli Studi di Milano-Bicocca, 20900 Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6962-049X","authenticated-orcid":false,"given":"Paride","family":"Mantecca","sequence":"additional","affiliation":[{"name":"Department of Earth and Environmental Sciences, Research Center POLARIA, Universita degli Studi di Milano-Bicocca, 20900 Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiziano","family":"Catelani","sequence":"additional","affiliation":[{"name":"Interdepartmental Microscopy Platform, University of Milano-Bicocca, 20126 Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michal","family":"Natan","sequence":"additional","affiliation":[{"name":"The Institute for Advanced Materials and Nanotechnology, The Mina and Everard Goodman Faculty of Life Sciences, Bar-Ilan University, Ramat-Gan 52900, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ehud","family":"Banin","sequence":"additional","affiliation":[{"name":"The Institute for Advanced Materials and Nanotechnology, The Mina and Everard Goodman Faculty of Life Sciences, Bar-Ilan University, Ramat-Gan 52900, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gila","family":"Jacobi","sequence":"additional","affiliation":[{"name":"The Institute for Advanced Materials and Nanotechnology, The Mina and Everard Goodman Faculty of Life Sciences, Bar-Ilan University, Ramat-Gan 52900, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8568-1110","authenticated-orcid":false,"given":"Tzanko","family":"Tzanov","sequence":"additional","affiliation":[{"name":"Group of Molecular and Industrial Biotechnology, Chemical Engineering, Universitat Polit\u00e9cnica de Catalunya, 08222 Terrassa, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,7,7]]},"reference":[{"key":"ref_1","unstructured":"O\u2019Neill, J.
