As such, fast and precise detection methods are needed to help combat the problem. Herein, the synthesis method for an anti-methamphetamine Quenchbody (Q-body), a promising sensor for use in simple and convenient assays, has been described. The fluorescence intensity of the Q-body generated by two-site labeling of Escherichia coli produced anti-methamphetamine antigen-binding fragment (Fab) with TAMRA-C2-maleimide dyes increased 5.1-fold over background in the presence of a hydroxyl methamphetamine derivative, 3-[(2S)-2-(methylamino)propyl]phenol. This derivative has the closest structure to methamphetamine of the chemicals available for use in a laboratory. Our results indicate the potential use of this Q-body as a novel sensor for the on-site detection of methamphetamine, in such occasions as drug screening at workplace, suspicious substance identification, and monitoring patients during drug rehabilitation.<\/jats:p>","DOI":"10.3390\/mps3020043","type":"journal-article","created":{"date-parts":[[2020,6,12]],"date-time":"2020-06-12T05:02:24Z","timestamp":1591938144000},"page":"43","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Synthesis of Quenchbodies for One-Pot Detection of Stimulant Drug Methamphetamine"],"prefix":"10.3390","volume":"3","author":[{"given":"Hee-Jin","family":"Jeong","sequence":"first","affiliation":[{"name":"Department of Biological and Chemical Engineering, Hongik University, 2639 Sejong-ro, Jochiwon-eup, Sejong-si 30016, Korea"},{"name":"Department of Chemical System Engineering, Hongik University, 2639 Sejong-ro, Jochiwon-eup, Sejong-si 30016, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7417-1932","authenticated-orcid":false,"given":"Jinhua","family":"Dong","sequence":"additional","affiliation":[{"name":"Key Laboratory of Biological Medicines in Universities of Shandong Province, Weifang Key Laboratory of Antibody Medicines, School of Bioscience and Technology, Weifang Medical University, Shandong 261053, China"},{"name":"World Research Hub Initiative, Institute of Innovative Research, Tokyo Institute of Technology, 4259 Nagatsuta-cho, Midori-ku, Yokohama, Kanagawa 226-8503, Japan"},{"name":"Laboratory for Chemistry and Life Science, Institute of Innovative Research, Tokyo Institute of Technology, 4259 Nagatsuta-cho, Midori-ku, Yokohama, Kanagawa 226-8503, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chang-Hun","family":"Yeom","sequence":"additional","affiliation":[{"name":"Department of Chemical System Engineering, Hongik University, 2639 Sejong-ro, Jochiwon-eup, Sejong-si 30016, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8849-4217","authenticated-orcid":false,"given":"Hiroshi","family":"Ueda","sequence":"additional","affiliation":[{"name":"Laboratory for Chemistry and Life Science, Institute of Innovative Research, Tokyo Institute of Technology, 4259 Nagatsuta-cho, Midori-ku, Yokohama, Kanagawa 226-8503, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,6,11]]},"reference":[{"key":"ref_1","first-page":"301","article-title":"The need for speed: An update on methamphetamine addiction","volume":"31","author":"Barr","year":"2006","journal-title":"J.
