There is a great need for the development of diagnostic tests, which are reliable, sensitive, stable, and low cost to enable early diagnosis of TB in communities with scarce resources. This study reports the optimization and evaluation of a synthetic receptor, an aptamer, for the detection of the secreted protein MPT64, which is a highly immunogenic polypeptide of <em>Mycobacterium tuberculosis<\/em>, a causative agent of TB.\u00a0The developed aptamer-based electrochemical impedance \u00a0sensor was successfully used with spiked human serum sample with a limit of detection of 81 pM. This work demonstrates the use of the MPT64 aptamer as a lower cost, more sustainable and stable alternative of antibodies for the development of point-of-care TB biosensors decreasing the detection time from several days or hours to thirty minutes..<\/p>\n<p>&nbsp;<\/p>\n<p class=\"Head\"><span class=\"title-text\"><span class=\"content\"><span class=\"text given-name\">Marzhan Sypabekova, Pawan Jolly,\u00a0<\/span><\/span><span class=\"content\"><span class=\"text given-name\">Pedro <\/span><span class=\"text surname\">Estrela, Damira Kanayeva<\/span><\/span><span class=\"content\"><span class=\"text surname\">:<\/span><\/span><\/span><\/p>\n<p class=\"Head\"><span class=\"title-text\">\"Electrochemical Aptasensor using Optimized Surface Chemistry for the Detection of <em>Mycobacterium tuberculosis<\/em> Secreted Protein MPT64 in Human Serum\"<\/span><\/p>\n<div id=\"banner\" class=\"Banner\">\n<div class=\"wrapper truncated\">\n<div class=\"AuthorGroups\">\n<div id=\"author-group\" class=\"author-group\"><a href=\"https:\/\/doi.org\/10.1016\/j.bios.2018.07.053\" target=\"_blank\" rel=\"noopener\"><strong><em>Biosensors and Bioelectronics<\/em>, in press<\/strong><\/a><\/div>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Tuberculosis (TB) remains one of the leading causes of mortality worldwide.
