To widen this panorama about MnO2 NPs, the formation of this material by laser ablation and deposition by dip-coating on fluorine-doped tin oxide (FTO), were considered in this study. The optical, spectroscopic, electrochemical characterization, and the evaluation of the antimicrobial activity, plus the photocatalytic response, were measured herein in colloidal media and deposited. For the deposition of NPs on FTO sheet, an anode is produced with a pseudocapacitive behavior, and 2.82 eV of band gap (GAP) in comparison with colloidal NPs for a value of 3.84 eV. Both colloidal suspension and deposited NPs have intrinsic antibacterial activity against two representative microorganisms (E. coli and S. aureus), and this biological activity was significantly enhanced in the presence of UVA light, indicating photocatalytic activity of the material. Thus, both the colloidal suspension and deposited NPs can act as disinfecting agents themselves or via light activation. However, an antibacterial behavior different for E. coli and S. aureus was observed, in function of the aggregation state, obtaining total E. coli disinfection at 30 min for deposited samples on FTO.<\/jats:p>","DOI":"10.3390\/nano12224061","type":"journal-article","created":{"date-parts":[[2022,11,18]],"date-time":"2022-11-18T04:08:40Z","timestamp":1668744520000},"page":"4061","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Manganese Dioxide Nanoparticles Prepared by Laser Ablation as Materials with Interesting Electronic, Electrochemical, and Disinfecting Properties in Both Colloidal Suspensions and Deposited on Fluorine-Doped Tin Oxide"],"prefix":"10.3390","volume":"12","author":[{"given":"Jhonatan","family":"Corrales","sequence":"first","affiliation":[{"name":"Maester in Chemical Sciencies, Faculty of technology, Universidad Tecnol\u00f3gica de Pereira, Pereira 660003, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jorge","family":"Acosta","sequence":"additional","affiliation":[{"name":"Department of Macromolecular Compounds, Faculty of Chemistry, Lomonosov Moscow State University MSU, 119991 Moscow, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2023-8935","authenticated-orcid":false,"given":"Sandra","family":"Castro","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Elctroqu\u00edmica y Medio Ambiente, Universidad Santiago de Cali, Faculty of Sciences, Santiago de Cali 760035, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6710-6526","authenticated-orcid":false,"given":"Henry","family":"Riascos","sequence":"additional","affiliation":[{"name":"Grupo de Ablaci\u00f3n L\u00e1ser, Universidad Tecnol\u00f3gica de Pereira, Pereira 660001, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5569-7878","authenticated-orcid":false,"given":"Efraim","family":"Serna-Galvis","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n Catalizadores y Adsorbentes (Catalad), Faculty of Exact and Natural Sciences, Chemistry Institution, Universidad de Antioquia UdeA, Calle 70 No. 52-21, Medell\u00edn 050010, Colombia"},{"name":"Grupo de Investigaci\u00f3n en Remediaci\u00f3n Ambiental y Biocat\u00e1lisis (GIRAB), Faculty of Exact and Natural Sciences, Chemistry Institution, Universidad de Antioquia UdeA, Calle 70 No. 52-21, Medell\u00edn 050010, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4583-9849","authenticated-orcid":false,"given":"Ricardo A.","family":"Torres-Palma","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Remediaci\u00f3n Ambiental y Biocat\u00e1lisis (GIRAB), Faculty of Exact and Natural Sciences, Chemistry Institution, Universidad de Antioquia UdeA, Calle 70 No. 52-21, Medell\u00edn 050010, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yenny","family":"\u00c1vila-Torres","sequence":"additional","affiliation":[{"name":"Grupo de Investigaci\u00f3n en Remediaci\u00f3n Ambiental y Biocat\u00e1lisis (GIRAB), Faculty of Exact and Natural Sciences, Chemistry Institution, Universidad de Antioquia UdeA, Calle 70 No. 52-21, Medell\u00edn 050010, Colombia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"275702","DOI":"10.1088\/1361-6528\/aa7454","article-title":"The shell effect on the room temperature photoluminescence from ZnO\/MgO core\/shell nanowires: Exciton\u2013phonon coupling and strain","volume":"28","author":"Vega","year":"2017","journal-title":"Nanotechnology"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"56","DOI":"10.1016\/j.jallcom.2019.03.115","article-title":"Structural, optical and vibrational properties of ZnO:M (M=Al3+ and Sr2+) nano and micropowders grown by hydrothermal synthesis","volume":"789","author":"Marin","year":"2019","journal-title":"J.
