In this work, we introduce dual-parameter optical sensors with fiber tips into the microfluidic chip. Multiple sensors were distributed in each channel of the chip, which enabled the real-time monitoring of the concentration and temperature of the microfluidics. The temperature sensitivity and glucose concentration sensitivity could reach 314 pm\/\u00b0C and \u22120.678 dB\/(g\/L), respectively. The hemispherical probe hardly affected the microfluidic flow field. The integrated technology combined the optical fiber sensor with the microfluidic chip and was low cost with high performance. Therefore, we believe that the proposed microfluidic chip integrated with the optical sensor is beneficial for drug discovery, pathological research and material science investigation. The integrated technology has great application potential for micro total analysis systems (\u03bc-TAS).<\/jats:p>","DOI":"10.3390\/s23052478","type":"journal-article","created":{"date-parts":[[2023,2,23]],"date-time":"2023-02-23T04:59:44Z","timestamp":1677128384000},"page":"2478","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Microfluidic Chip with Fiber-Tip Sensors for Synchronously Monitoring Concentration and Temperature of Glucose Solutions"],"prefix":"10.3390","volume":"23","author":[{"given":"Jian","family":"Qu","sequence":"first","affiliation":[{"name":"Center for Composite Materials, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Physics, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9670-6339","authenticated-orcid":false,"given":"Yan","family":"Li","sequence":"additional","affiliation":[{"name":"School of Physics, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8085-5599","authenticated-orcid":false,"given":"Jinjian","family":"Li","sequence":"additional","affiliation":[{"name":"School of Physics, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Songhe","family":"Meng","sequence":"additional","affiliation":[{"name":"Center for Composite Materials, Harbin Institute of Technology, Harbin 150001, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"3603","DOI":"10.1039\/D2LC00188H","article-title":"Flowmetering for microfluidics","volume":"22","author":"Cavaniol","year":"2022","journal-title":"Lab Chip"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"5","DOI":"10.29026\/oea.2019.190007","article-title":"Optofluidics: The interaction between light and flowing liquids in integrated devices","volume":"2","author":"Zhu","year":"2019","journal-title":"Opto-Electron.
