The morphologies of Ag-ZnO nanoplates were examined by scanning electron microscopy. It was found that under an optimum condition (pH 7.0), the oxidation of d-penicillamine at the surface of such an electrode occurs at a potential about 165 mV less positive than that of an unmodified carbon paste electrode. The diffusion coefficient (D = 7.6 \u00d7 10\u22126 cm2\/s) and the electron transfer coefficient (\u03b1 = 0.54) for d-penicillamine oxidation were also determined. The proposed method exhibited a wide linear dynamic range of 0.03\u2013250.0 \u00b5M, with an LOD (S\/N = 3) of 0.015 \u00b5M. Moreover, the modified electrode exhibited good reproducibility and high selectivity, demonstrating its feasibility for the analytical purpose. Lastly, this new sensor was used for the determination of d-penicillamine and tryptophan in real samples.<\/jats:p>","DOI":"10.5740\/jaoacint.16-0361","type":"journal-article","created":{"date-parts":[[2017,8,1]],"date-time":"2017-08-01T11:05:16Z","timestamp":1501585516000},"page":"208-215","source":"Crossref","is-referenced-by-count":7,"title":["First Report for Determination of d-Penicillamine in the Presence of Tryptophan Using a 2-Chlorobenzoyl Ferrocene\/Ag-Supported ZnO Nanoplate\u2013Modified Carbon Paste Electrode"],"prefix":"10.1093","volume":"101","author":[{"given":"Hadi","family":"Beitollahi","sequence":"first","affiliation":[{"name":"Graduate University of Advanced Technology, Institute of Science and High Technology and Environmental Sciences, Environment Department, Kerman, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Abbas","family":"Gholami","sequence":"additional","affiliation":[{"name":"Graduate University of Advanced Technology, Department of Chemistry, Kerman, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohammad Reza","family":"Ganjali","sequence":"additional","affiliation":[{"name":"University of Tehran, Center of Excellence in Electrochemistry, Tehran, Iran; Tehran University of Medical Sciences, Endocrinology and Metabolism Molecular-Cellular Sciences Institute, Biosensor Research Center, Tehran, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2019,11,23]]},"container-title":["Journal of AOAC INTERNATIONAL"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/101\/1\/208\/32427774\/jaoac0208.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/academic.oup.com\/jaoac\/article-pdf\/101\/1\/208\/32427774\/jaoac0208.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T18:16:29Z","timestamp":1584641789000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/jaoac\/article\/101\/1\/208-215\/5653894"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,1,1]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2019,11,23]]},"published-print":{"date-parts":[[2018,1,1]]}},"URL":"https:\/\/doi.org\/10.5740\/jaoacint.16-0361","relation":{},"ISSN":["1060-3271","1944-7922"],"issn-type":[{"value":"1060-3271","type":"print"},{"value":"1944-7922","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2018,1,1]]},"published":{"date-parts":[[2018,1,1]]}}}
