Due to its high toxicity sensitive analytical methods are highly important, taking into account that the admitted level is in the range of \u00b5g L\u22121. A novel and easy to use platform for As(III) detection from water samples is proposed, based on gold and platinum bi metallic nanoparticles and a conductive polymer (polyaniline). The electrochemical detection was achieved after optimization of cathodic pre-concentration and stripping parameters by square wave anodic stripping voltammetry at modified screen-printed carbon-based electrochemical cells, proving its applicability for disposable and cost-effective in situ analysis of arsenic.<\/jats:p>","DOI":"10.3390\/s19102279","type":"journal-article","created":{"date-parts":[[2019,5,17]],"date-time":"2019-05-17T11:06:46Z","timestamp":1558091206000},"page":"2279","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Electrochemical Fingerprint of Arsenic (III) by Using Hybrid Nanocomposite-Based Platforms"],"prefix":"10.3390","volume":"19","author":[{"given":"Gheorghe","family":"Melinte","sequence":"first","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Pharmacy, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, Pasteur 4, 400349 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Oana","family":"Hosu","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Pharmacy, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, Pasteur 4, 400349 Cluj-Napoca, Romania"},{"name":"Department of Chemistry \u201dUgo Schiff\u201d, University of Florence, Via della Lastruccia 3, 50019 Sesto Fiorentino (Fi), Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mariagrazia","family":"Lettieri","sequence":"additional","affiliation":[{"name":"Department of Chemistry \u201dUgo Schiff\u201d, University of Florence, Via della Lastruccia 3, 50019 Sesto Fiorentino (Fi), Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4158-3324","authenticated-orcid":false,"given":"Cecilia","family":"Cristea","sequence":"additional","affiliation":[{"name":"Department of Analytical Chemistry, Faculty of Pharmacy, \u201cIuliu Ha\u0163ieganu\u201d University of Medicine and Pharmacy, Pasteur 4, 400349 Cluj-Napoca, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2465-7552","authenticated-orcid":false,"given":"Giovanna","family":"Marrazza","sequence":"additional","affiliation":[{"name":"Department of Chemistry \u201dUgo Schiff\u201d, University of Florence, Via della Lastruccia 3, 50019 Sesto Fiorentino (Fi), Italy"},{"name":"Instituto Nazionale Biostrutture e Biosistemi (INBB), Unit of Florence, Viale delle Medaglie d\u2019Oro 305, 00136 Roma, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,5,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"931","DOI":"10.1002\/elan.201400041","article-title":"Stripping Analysis of As(III) by means of screen-printed electrodes modified with gold nanoparticles and carbon black nanocomposite","volume":"26","author":"Cinti","year":"2014","journal-title":"Electroanalysis"},{"key":"ref_2","first-page":"38","article-title":"Metabolism and toxicity of arsenic: A human carcinogen Sources of different forms of arsenic: Human exposure and chronic arsenicism","volume":"82","author":"Roy","year":"2002","journal-title":"Curr.
