Tubes are a highly portable and accessible container shape which are widely used for scientific research in cell biology and chemical synthesis, and which are also of great use in domestic health care applications. Here, we show for the first time the development of a tube-based painted amperometric biosensor for the detection of glucose and lactate. The sensor was prepared by printing carbon graphite and silver\/silver chloride inks on the interior wall of the tube and then immobilizing glucose oxidase or lactate oxidase on the sensor. The sensor showed a sensitive, rapid, and reliable detection of glucose and lactate. We anticipate that these results could open new avenues for the development of painted biosensors, and toward advanced biosensor applications.<\/jats:p>","DOI":"10.3390\/s18051620","type":"journal-article","created":{"date-parts":[[2018,5,21]],"date-time":"2018-05-21T04:07:30Z","timestamp":1526875650000},"page":"1620","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["A Tube-Integrated Painted Biosensor for Glucose and Lactate"],"prefix":"10.3390","volume":"18","author":[{"given":"Weihua","family":"Shi","sequence":"first","affiliation":[{"name":"College of Engineering, Peking University, Beijing 100871, China"}]},{"given":"Xiaojin","family":"Luo","sequence":"additional","affiliation":[{"name":"College of Engineering, Peking University, Beijing 100871, China"}]},{"given":"Yue","family":"Cui","sequence":"additional","affiliation":[{"name":"College of Engineering, Peking University, Beijing 100871, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,5,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"256","DOI":"10.1080\/09513590.2017.1390737","article-title":"Identification and prediction of the fertile window with a new web-based medical device using a vaginal biosensor for measuring the circadian and circamensual core body temperature","volume":"34","author":"Regidor","year":"2018","journal-title":"Gynecol.
