The depollution effect is largely enhanced by UVC irradiation. The novelty of this contribution comes from the significant increase by packing of the total surface of metamaterials in contact with contaminated fluids. Packed metamaterial samples are subjected to UVC irradiation, with expected advantages for implant sterilization and long-term prevention of nosocomial infections over large clinical areas. The novel aspect of the investigation consists of a combination of big and small elements of the metamaterial to optimize the above effects connected with fluids and irradiation. The big elements allow the radiation to penetrate deep inside the fluid, and the small elements optimally disperse this radiation toward deeper regions of the metamaterial. A packing scheme of smaller, in-between large metamaterial spheres and fibres is proposed for promoting enhanced depollution against pathogen agents. It is demonstrated that the total surface of metamaterials in contact with contaminated fluids\/surface is significantly increased as a result of packing. This opens, in our opinion, new auspicious perspectives in the construction of novel equipment with high sensibility in the detection and decontamination of microorganisms.<\/jats:p>","DOI":"10.3390\/ma16134559","type":"journal-article","created":{"date-parts":[[2023,6,26]],"date-time":"2023-06-26T05:11:54Z","timestamp":1687756314000},"page":"4559","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Topological Avenue for Efficient Decontamination of Large Volumes of Fluids via UVC Irradiation of Packed Metamaterials"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4571-7457","authenticated-orcid":false,"given":"Nicolae A.","family":"Enaki","sequence":"first","affiliation":[{"name":"Quantum Optics and Kinetic Processes Laboratory, Institute of Applied Physics, Moldova State University, 5 Academiei Str., MD2028 Chi\u0219in\u0103u, Moldova"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5685-8888","authenticated-orcid":false,"given":"Ion","family":"Munteanu","sequence":"additional","affiliation":[{"name":"Quantum Optics and Kinetic Processes Laboratory, Institute of Applied Physics, Moldova State University, 5 Academiei Str., MD2028 Chi\u0219in\u0103u, Moldova"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatiana","family":"Paslari","sequence":"additional","affiliation":[{"name":"Quantum Optics and Kinetic Processes Laboratory, Institute of Applied Physics, Moldova State University, 5 Academiei Str., MD2028 Chi\u0219in\u0103u, Moldova"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marina","family":"Turcan","sequence":"additional","affiliation":[{"name":"Quantum Optics and Kinetic Processes Laboratory, Institute of Applied Physics, Moldova State University, 5 Academiei Str., MD2028 Chi\u0219in\u0103u, Moldova"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elena","family":"Starodub","sequence":"additional","affiliation":[{"name":"Quantum Optics and Kinetic Processes Laboratory, Institute of Applied Physics, Moldova State University, 5 Academiei Str., MD2028 Chi\u0219in\u0103u, Moldova"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1660-9147","authenticated-orcid":false,"given":"Sergiu","family":"Bazgan","sequence":"additional","affiliation":[{"name":"Quantum Optics and Kinetic Processes Laboratory, Institute of Applied Physics, Moldova State University, 5 Academiei Str., MD2028 Chi\u0219in\u0103u, Moldova"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diana","family":"Podoleanu","sequence":"additional","affiliation":[{"name":"Quantum Optics and Kinetic Processes Laboratory, Institute of Applied Physics, Moldova State University, 5 Academiei Str., MD2028 Chi\u0219in\u0103u, Moldova"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8433-9217","authenticated-orcid":false,"given":"Carmen","family":"Ristoscu","sequence":"additional","affiliation":[{"name":"Laser-Surface-Plasma Interactions Laboratory, National Institute for Lasers, Plasma and Radiation Physics (INFLPR), Magurele, Ilfov, RO-077125 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sinziana","family":"Anghel","sequence":"additional","affiliation":[{"name":"Laser-Surface-Plasma Interactions Laboratory, National Institute for Lasers, Plasma and Radiation Physics (INFLPR), Magurele, Ilfov, RO-077125 Bucharest, Romania"},{"name":"Faculty of Physics, University of Bucharest, Magurele, Ilfov, RO-77125 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Maria","family":"Badiceanu","sequence":"additional","affiliation":[{"name":"Laser-Surface-Plasma Interactions Laboratory, National Institute for Lasers, Plasma and Radiation Physics (INFLPR), Magurele, Ilfov, RO-077125 Bucharest, Romania"},{"name":"Faculty of Physics, University of Bucharest, Magurele, Ilfov, RO-77125 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9486-0420","authenticated-orcid":false,"given":"Ion N.","family":"Mihailescu","sequence":"additional","affiliation":[{"name":"Laser-Surface-Plasma Interactions Laboratory, National Institute for Lasers, Plasma and Radiation Physics (INFLPR), Magurele, Ilfov, RO-077125 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,6,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"111999","DOI":"10.1016\/j.jphotobiol.2020.111999","article-title":"Light-based technologies for management of COVID-19 pandemic crisis","volume":"212","author":"Sabino","year":"2020","journal-title":"J.
