The device is fully made of Cyclo-Olefin Copolymer (COC), which features low auto-fluorescence, biocompatibility and manufacturability by hot-embossing. The RNA retrieval was carried on after bacteria heat-lysis by an on-chip micro-heater, whose function was characterized at different working parameters. Carbon resistive temperature sensors were tested, characterized and printed on the biochip sealing film to monitor the heating process. Off-chip and on-chip processed RNA were hybridized with capture probes on the reaction chamber surface and identification was achieved by detection of fluorescence tags. The application of the mentioned techniques and materials proved to allow the development of low-cost, disposable albeit multi-functional microfluidic system, performing heating, temperature sensing and chemical reaction processes in the same device. By proving its effectiveness, this device contributes a reference to show the integration potential of fully thermoplastic devices in biosensor systems.<\/jats:p>","DOI":"10.3390\/s19051178","type":"journal-article","created":{"date-parts":[[2019,3,8]],"date-time":"2019-03-08T04:58:35Z","timestamp":1552021115000},"page":"1178","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Design and Manufacturing of a Disposable, Cyclo-Olefin Copolymer, Microfluidic Device for a Biosensor \u2020"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7496-8319","authenticated-orcid":false,"given":"Jorge","family":"Prada","sequence":"first","affiliation":[{"name":"Institut f\u00fcr Mikrosensoren, -Aktoren und -Systeme, Universit\u00e4t Bremen, 28359 Bremen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christina","family":"Cordes","sequence":"additional","affiliation":[{"name":"Bremerhavener Institut f\u00fcr Angewandte Molekularbiologie, Hochschule Bremerhaven, 27568 Bremerhaven, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carsten","family":"Harms","sequence":"additional","affiliation":[{"name":"Bremerhavener Institut f\u00fcr Angewandte Molekularbiologie, Hochschule Bremerhaven, 27568 Bremerhaven, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Walter","family":"Lang","sequence":"additional","affiliation":[{"name":"Institut f\u00fcr Mikrosensoren, -Aktoren und -Systeme, Universit\u00e4t Bremen, 28359 Bremen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,3,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"8733","DOI":"10.1039\/c3cs60141b","article-title":"Biosensor technology: Recent advances in threat agent detection and medicine","volume":"42","author":"Kirsch","year":"2013","journal-title":"Chem.
