GO, RB and the obtained RB-PDDA-GO were characterized by scanning\n electron microscopy, transmission electron microscopy, Fourier transform infrared spectrometry, thermogravimetric analysis, Raman spectroscopy, UV-visible spectrophotometry, and X-ray photoelectron spectroscopy. The oxidation of hydroquinone to p-benzoquinone was used to evaluate the oxidation\n ability. Three kinds of reactive oxygen species (O<jats:sub>2<\/jats:sub><jats:sup>\u00b7-<\/jats:sup>, <jats:sup>1<\/jats:sup>O<jats:sub>2<\/jats:sub> and \u00b7OH) produced by the materials under light irradiation were detected by the ESR method using TEMP (2,2,6,6-tetramethyl-4-piperidine) and DMPO (5,5-dimethyl-1-pyrroline-N-oxide)\n as capture agents. The results showed that RB-PDDA-GO produced more ROS under light than GO. Antibacterial experiments were carried out with <jats:italic>E. coli<\/jats:italic> as the target strain to detect the actual utility of ROS produced by the materials. The results showed that RB-PDDA-GO had a significant\n sterilization effect.<\/jats:p>","DOI":"10.1166\/jnn.2020.18615","type":"journal-article","created":{"date-parts":[[2020,7,26]],"date-time":"2020-07-26T04:35:53Z","timestamp":1595738153000},"page":"7558-7568","source":"Crossref","is-referenced-by-count":3,"title":["Highly Efficient Photocatalytic Disinfection of <i>Escherichia coli<\/i> by Rose Bengal-Functionalized Graphene Oxide Nanosheets"],"prefix":"10.1166","volume":"20","author":[{"given":"Fenping","family":"Chi","sequence":"first","affiliation":[{"name":"Anhui Province Key Laboratory of Chemistry for Inorganic\/Organic Hybrid Functionalized Materials, School of Chemistry & Chemical Engineering, Anhui University, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pengpeng","family":"Chen","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Chemistry for Inorganic\/Organic Hybrid Functionalized Materials, School of Chemistry & Chemical Engineering, Anhui University, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changjie","family":"Mao","sequence":"additional","affiliation":[{"name":"Anhui Province Key Laboratory of Chemistry for Inorganic\/Organic Hybrid Functionalized Materials, School of Chemistry & Chemical Engineering, Anhui University, Hefei 230601, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"17","container-title":["Journal of Nanoscience and Nanotechnology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/asp\/jnn\/2020\/00000020\/00000012\/art00042","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,8,4]],"date-time":"2020-08-04T11:39:43Z","timestamp":1596541183000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.1166\/jnn.2020.18615"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,12,1]]},"references-count":0,"journal-issue":{"issue":"12","published-print":{"date-parts":[[2020,12,1]]}},"alternative-id":["1533-4880(20201201)20:12L.7558;1-"],"URL":"https:\/\/doi.org\/10.1166\/jnn.2020.18615","relation":{},"ISSN":["1533-4880"],"issn-type":[{"value":"1533-4880","type":"print"}],"subject":[],"published":{"date-parts":[[2020,12,1]]}}}
