The assay is based on a wipe test and is specifically designed for use in the field. The prototype instrument designed to run the assay is capable of performing time-resolved electrochemical measurements including cyclic square wave voltammetry using an embedded microcontroller with parts costing roughly $250 USD. We generated an example library of cyclic square wave voltammograms of 12 compounds including 10 nitroaromatics, a nitramine (RDX), and a nitrate ester (nitroglycine), and designed a simple discrimination algorithm based on this library data for identification.<\/jats:p>","DOI":"10.3390\/s17081769","type":"journal-article","created":{"date-parts":[[2017,8,2]],"date-time":"2017-08-02T10:05:25Z","timestamp":1501668325000},"page":"1769","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["A Simple and Inexpensive Electrochemical Assay for the Identification of Nitrogen Containing Explosives in the Field"],"prefix":"10.3390","volume":"17","author":[{"given":"Jeffrey","family":"Erickson","sequence":"first","affiliation":[{"name":"Center for Biomolecular Science and Engineering, Naval Research Laboratory, Washington, DC 20375, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lisa","family":"Shriver-Lake","sequence":"additional","affiliation":[{"name":"Center for Biomolecular Science and Engineering, Naval Research Laboratory, Washington, DC 20375, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel","family":"Zabetakis","sequence":"additional","affiliation":[{"name":"Center for Biomolecular Science and Engineering, Naval Research Laboratory, Washington, DC 20375, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Stenger","sequence":"additional","affiliation":[{"name":"Center for Biomolecular Science and Engineering, Naval Research Laboratory, Washington, DC 20375, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Scott","family":"Trammell","sequence":"additional","affiliation":[{"name":"Center for Biomolecular Science and Engineering, Naval Research Laboratory, Washington, DC 20375, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2017,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8146","DOI":"10.1021\/acs.chemrev.6b00065","article-title":"Chemical sniffing instrumentation for security applications","volume":"116","author":"Giannoukos","year":"2016","journal-title":"Chem.
