Developed at the S\u00e3o Carlos Institutes of Physics and Chemistry at the University of S\u00e3o Paulo (IFSC and IQSC at USP), the device is similar to the glucose monitors used by diabetics. It consists of a paper substrate and three carbon electrodes dipped in an acidic solution. \u201cWhen it comes into contact with a sample contaminated with carbendazim, the sensor induces an electrochemical oxidation reaction that detects the fungicide,\u201d Jos\u00e9 Luiz Bott Neto, one of the authors of the paper from the IFSC, told <em>Ag\u00eancia<\/em> <em>FAPESP<\/em>. According to Neto, the sensor presented similar results to conventional devices made of plastic or ceramic (<em>Food Chemistry<\/em>, June 1, 2022).<\/p>\n","protected":false},"excerpt":{"rendered":"Electrochemical sensor made of kraft paper connected to an electronic device can detect prohibited fungicide within minutes","protected":false},"author":475,"featured_media":481756,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[259,235,2413],"coauthors":[785],"class_list":["post-481846","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-notes","tag-chemistry","tag-physics","tag-technology"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/481846","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=481846"}],"version-history":[{"count":1,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/481846\/revisions"}],"predecessor-version":[{"id":481848,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/481846\/revisions\/481848"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media\/481756"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=481846"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=481846"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=481846"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=481846"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
