To move CCPCR technology forward toward commercialization, a couple of critical strategies and innovations are discussed here. First, single- and dual-end heating strategies are analyzed and compared between each other. Especially, different solutions for dual-end heating are proposed and discussed, and the heat transfer and fluid flow inside the capillary tube with an optimized dual-end heating strategy are analyzed and modeled. Second, real-time CCPCR is implemented with light-emitting diode and photodiode, and the real-time fluorescence detection method is compared with the post-amplification end-point detection method based on a dipstick assay. Thirdly, to reduce the system complexity, e.g., to simplify parameter tuning of the feedback control, an internal-model-control-based proportional-integral-derivative controller is adopted for accurate temperature control. Fourth, as a proof of concept, CCPCR with pre-loaded dry storage of reagent inside the capillary PCR tube is evaluated to better accommodate to point-of-care diagnosis. The critical performances of improved CCPCR, especially with sensitivity, repeatability, and reliability, have been thoroughly analyzed with different experiments using influenza A (H1N1) virus as the detection sample.<\/jats:p>","DOI":"10.1063\/1.4977841","type":"journal-article","created":{"date-parts":[[2017,3,31]],"date-time":"2017-03-31T12:04:52Z","timestamp":1490961892000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":19,"title":["Characterization and analysis of real-time capillary convective PCR toward commercialization"],"prefix":"10.1063","volume":"11","author":[{"given":"Xianbo","family":"Qiu","sequence":"first","affiliation":[{"name":"Beijing University of Chemical Technology 1 Institute of Microfluidic Chip Development in Biomedical Engineering, College of Information Science and Technology, , Beijing 100029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiyin","family":"Zhang","sequence":"additional","affiliation":[{"name":"Xiamen University 2 National Institute of Diagnostics and Vaccine Development in Infectious Diseases, , Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lanju","family":"Mei","sequence":"additional","affiliation":[{"name":"Old Dominion University 3 Institute of Micro\/Nanotechnology, , Norfolk, Virginia 23529, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Di","family":"Wu","sequence":"additional","affiliation":[{"name":"Beijing University of Chemical Technology 1 Institute of Microfluidic Chip Development in Biomedical Engineering, College of Information Science and Technology, , Beijing 100029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qi","family":"Guo","sequence":"additional","affiliation":[{"name":"Beijing University of Chemical Technology 1 Institute of Microfluidic Chip Development in Biomedical Engineering, College of Information Science and Technology, , Beijing 100029, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ke","family":"Li","sequence":"additional","affiliation":[{"name":"Beijing Wantai Biological Pharmacy Enterprise Co., Ltd. 4 , Beijing 102206, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengxiang","family":"Ge","sequence":"additional","affiliation":[{"name":"Xiamen University 2 National Institute of Diagnostics and Vaccine Development in Infectious Diseases, , Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangzhong","family":"Ye","sequence":"additional","affiliation":[{"name":"Beijing Wantai Biological Pharmacy Enterprise Co., Ltd. 4 , Beijing 102206, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ningshao","family":"Xia","sequence":"additional","affiliation":[{"name":"Xiamen University 2 National Institute of Diagnostics and Vaccine Development in Infectious Diseases, , Xiamen 361005, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael G.","family":"Mauk","sequence":"additional","affiliation":[{"name":"University of Pennsylvania 5 Department of Mechanical Engineering and Applied Mechanics, , Philadelphia, Pennsylvania 19104, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"317","published-online":{"date-parts":[[2017,3,3]]},"reference":[{"key":"2023062511512870500_c1","doi-asserted-by":"publisher","first-page":"3170","DOI":"10.1039\/c0lc00038h","volume":"10","year":"2010","journal-title":"Lab Chip"},{"key":"2023062511512870500_c2","doi-asserted-by":"publisher","first-page":"3249","DOI":"10.1039\/c2lc40630f","volume":"12","year":"2012","journal-title":"Lab Chip"},{"key":"2023062511512870500_c3","doi-asserted-by":"publisher","first-page":"2995","DOI":"10.1021\/ac991471a","volume":"72","year":"2000","journal-title":"Anal.
