The device, which measures just a few centimeters, uses biochemical and electrochemical methods to recognize molecules on the surface of cancer cells, using an electrical current and folic acid, a complex B vitamin. It comprises a polymer micro-channel and a silicone layer, where the folic acid biosensors are placed, to which the cancer cells attach themselves if they are present in the solution (blood plasma) that flows within the micro-channel. The electrodes are installed in a third layer, made from glass. If a tumor is detected electrochemical information is sent to them, changing the electrical information and causing a difference in the signal of the current detected by the biosensor. \u201cIt differs from other biosensor projects in that the electrodes aren\u2019t in direct contact with the solution,\u201d explains Emanuel Carrilho from USP\u2019s S\u00e3o Carlos Institute of Chemistry, the project coordinator. <\/p>\n","protected":false},"excerpt":{"rendered":"Biosensors detect cancer","protected":false},"author":6,"featured_media":0,"comment_status":"open","ping_status":"open","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":[168],"tags":[211,243,247],"coauthors":[93],"class_list":["post-6857","post","type-post","status-publish","format-standard","hentry","category-technoscience","tag-biochemistry","tag-innovation","tag-medicine"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/6857","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\/6"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=6857"}],"version-history":[{"count":0,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/6857\/revisions"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=6857"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=6857"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=6857"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=6857"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
