However, AuNPs are used in applications where chemical reactions involving transient radicals occur. Herein, we investigate AuNPs\u2019 catalytic effect on 2-propanol oxidation and acetanilide hydroxylation in aqueous solutions under ionizing radiation at room temperature. In both cases, the presence of AuNPs led to selective oxidation of organic radicals, significantly changing the products\u2019 composition and ratio. Based on these observations, we stress how AuNPs\u2019 catalytic activity can affect the correctness of reactive oxygen species concentration determination utilizing organic dyes. We also provide a discussion on the role of AuNPs\u2019 catalytic activity in the radiosensitization effect actively studied for radiotherapy.<\/jats:p>","DOI":"10.3390\/nano11030727","type":"journal-article","created":{"date-parts":[[2021,3,14]],"date-time":"2021-03-14T23:52:06Z","timestamp":1615765926000},"page":"727","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Selective Oxidation of Transient Organic Radicals in the Presence of Gold Nanoparticles"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3628-1804","authenticated-orcid":false,"given":"Viacheslav","family":"Shcherbakov","sequence":"first","affiliation":[{"name":"Institute de Chimie Physique (ICP), CNRS\/Universit\u00e9 Paris-Saclay, 91405 Orsay, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7881-1979","authenticated-orcid":false,"given":"Sergey A.","family":"Denisov","sequence":"additional","affiliation":[{"name":"Institute de Chimie Physique (ICP), CNRS\/Universit\u00e9 Paris-Saclay, 91405 Orsay, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mehran","family":"Mostafavi","sequence":"additional","affiliation":[{"name":"Institute de Chimie Physique (ICP), CNRS\/Universit\u00e9 Paris-Saclay, 91405 Orsay, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"11","DOI":"10.1007\/BF03215149","article-title":"The catalytic properties of gold","volume":"5","author":"Bond","year":"1972","journal-title":"Gold Bull."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"102","DOI":"10.1007\/BF03215018","article-title":"Gold catalysts for olefin hydrogenation\u2014Transmutation of catalytic properties","volume":"6","author":"Bond","year":"1973","journal-title":"Gold Bull."},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"405","DOI":"10.1246\/cl.1987.405","article-title":"Novel Gold Catalysts for the Oxidation of Carbon Monoxide at a Temperature far Below 0 \u00b0C","volume":"16","author":"Haruta","year":"1987","journal-title":"Chem.
