DBD plasma-treated samples showed higher AgNP deposition than untreated ones for all methods. After five washing cycles, only DBD plasma-treated samples displayed AgNPs on the fabric surface. The best-performing method was exhaustion at 30 \u00b0C, which exhibited less agglomeration and the best antibacterial efficacy against S. aureus (4 log reduction). For E. coli, the antimicrobial effect showed good results in all the exhaustion samples (5 log reduction). Considering the spray method, only the DBD plasma-treated samples showed some bacteriostatic activity for both strains, but the AgNP concentration was not enough to have a bactericidal effect. Our results suggest DBD plasma may be a low cost and chemical-free method for the preparation of antibacterial textiles, allowing for the immobilization of a very low\u2014but effective\u2014concentration of AgNPs.<\/jats:p>","DOI":"10.3390\/coatings9090581","type":"journal-article","created":{"date-parts":[[2019,9,16]],"date-time":"2019-09-16T03:17:57Z","timestamp":1568603877000},"page":"581","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Antimicrobial Efficacy of Low Concentration PVP-Silver Nanoparticles Deposited on DBD Plasma-Treated Polyamide 6,6 Fabric"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9556-6311","authenticated-orcid":false,"given":"Ana","family":"Ribeiro","sequence":"first","affiliation":[{"name":"2C2T-Centro de Ci\u00eancia e Tecnologia T\u00eaxtil, Universidade do Minho, Campus de Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]},{"given":"Dilara","family":"Senturk","sequence":"additional","affiliation":[{"name":"2C2T-Centro de Ci\u00eancia e Tecnologia T\u00eaxtil, Universidade do Minho, Campus de Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]},{"given":"K\u00e9sia","family":"Silva","sequence":"additional","affiliation":[{"name":"Department of Textile Engineering, Federal University of Rio Grande do Norte, Natal\/RN 1524, Brazil"}]},{"given":"Martina","family":"Modic","sequence":"additional","affiliation":[{"name":"Jo\u017eef Stefan Institute, 1000 Ljubljana, Slovenia"}]},{"given":"Uros","family":"Cvelbar","sequence":"additional","affiliation":[{"name":"Jo\u017eef Stefan Institute, 1000 Ljubljana, Slovenia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2179-1609","authenticated-orcid":false,"given":"Gheorghe","family":"Dinescu","sequence":"additional","affiliation":[{"name":"National Institute for Lasers, Plasma and Radiation Physics, 077125 M\u0103gurele, Romania"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0603-4864","authenticated-orcid":false,"given":"Bogdana","family":"Mitu","sequence":"additional","affiliation":[{"name":"National Institute for Lasers, Plasma and Radiation Physics, 077125 M\u0103gurele, Romania"}]},{"given":"Anton","family":"Nikiforov","sequence":"additional","affiliation":[{"name":"Department of Applied Physics, Ghent University, 9000 Ghent, Belgium"}]},{"given":"Christophe","family":"Leys","sequence":"additional","affiliation":[{"name":"Department of Applied Physics, Ghent University, 9000 Ghent, Belgium"}]},{"given":"Irina","family":"Kuchakova","sequence":"additional","affiliation":[{"name":"Department of Applied Physics, Ghent University, 9000 Ghent, Belgium"}]},{"given":"Mike","family":"De Vrieze","sequence":"additional","affiliation":[{"name":"Centexbel Ghent, Technologie park 7, 9052 Ghent, Belgium"}]},{"given":"Ant\u00f3nio","family":"Souto","sequence":"additional","affiliation":[{"name":"2C2T-Centro de Ci\u00eancia e Tecnologia T\u00eaxtil, Universidade do Minho, Campus de Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5299-4164","authenticated-orcid":false,"given":"Andrea","family":"Zille","sequence":"additional","affiliation":[{"name":"2C2T-Centro de Ci\u00eancia e Tecnologia T\u00eaxtil, Universidade do Minho, Campus de Azur\u00e9m, 4800-058 Guimar\u00e3es, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2019,9,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"50","DOI":"10.1038\/s41429-018-0111-6","article-title":"Augmented antibacterial activity of ampicillin with silver nanoparticles against methicillin-resistant Staphylococcus aureus (MRSA)","volume":"72","author":"Surwade","year":"2018","journal-title":"J.
