A resin substrate immersed in an aqueous solution of silver nitrate was irradiated with gamma ray or high energy electron beams. Silver nanoparticles were successfully immobilized on the resin surface directly by chemical reactions induced by ionizing radiation. It was experimentally confirmed that various resin materials, such as acrylonitrile-butadiene-styrene, polyethylene, polypropylene, polyvinyl chloride, and polycarbonate, were applicable for this process. The effects of gamma ray or electron beam irradiation on resin substrates were almost negligible since the irradiation dose was equal or less than that used for sterilization. Despite the small amount of Ag loadings, the obtained samples showed high antibacterial and antiviral activities.<\/jats:p>","DOI":"10.3390\/nano12173046","type":"journal-article","created":{"date-parts":[[2022,9,7]],"date-time":"2022-09-07T01:51:57Z","timestamp":1662515517000},"page":"3046","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Development of Direct Immobilization Technique of Ag Nanoparticles on Resin Substrates Imparting High Antibacterial and Antiviral Activities"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3770-5667","authenticated-orcid":false,"given":"Satoshi","family":"Seino","sequence":"first","affiliation":[{"name":"Graduate School of Engineering, Osaka University, 2-1 Yamadaoka, Suita 565-0871, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7366-5108","authenticated-orcid":false,"given":"Yuji","family":"Ohkubo","sequence":"additional","affiliation":[{"name":"Graduate School of Engineering, Osaka University, 2-1 Yamadaoka, Suita 565-0871, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomonari","family":"Magara","sequence":"additional","affiliation":[{"name":"Graduate School of Engineering, Osaka University, 2-1 Yamadaoka, Suita 565-0871, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hiroki","family":"Enomoto","sequence":"additional","affiliation":[{"name":"Graduate School of Engineering, Osaka University, 2-1 Yamadaoka, Suita 565-0871, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eri","family":"Nakajima","sequence":"additional","affiliation":[{"name":"Japan Textile Products Quality and Technology Center, 5-7-3, Shimoyamate-dori, Chuo-ku, Kobe-City 650-0011, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7330-8765","authenticated-orcid":false,"given":"Tomoki","family":"Nishida","sequence":"additional","affiliation":[{"name":"Japan Textile Products Quality and Technology Center, 5-7-3, Shimoyamate-dori, Chuo-ku, Kobe-City 650-0011, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuo","family":"Imoto","sequence":"additional","affiliation":[{"name":"Japan Textile Products Quality and Technology Center, 5-7-3, Shimoyamate-dori, Chuo-ku, Kobe-City 650-0011, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Takashi","family":"Nakagawa","sequence":"additional","affiliation":[{"name":"Graduate School of Engineering, Osaka University, 2-1 Yamadaoka, Suita 565-0871, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,9,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"76","DOI":"10.1016\/j.biotechadv.2008.09.002","article-title":"Silver nanoparticles as a new generation of antimicrobials","volume":"27","author":"Rai","year":"2009","journal-title":"Biotechnol.
