Platinum nanoparticles (PtNP) were electrochemically deposited on the modified GRGO\/AC surface, and chitosan-glucose oxidase (Chit-GOx) composites and nafion were integrated onto the modified surface of the working electrode to prepare a highly sensitive glucose sensor. The fabricated biosensor exhibited a good amperometric response to glucose in the detection range from 0.002\u2009mM to 10\u2009mM, with a sensitivity of 61.06\u2009\u03bcA\/mMcm<jats:sup>2<\/jats:sup>, a short response time (4 s) and a low detection limit of 2\u2009\u03bcM (signal to noise ratio is 3). The glucose sensor exhibited a negligible response to interference and good stability. In addition, the glucose levels in human urine were tested in order to conduct a practical assessment of the proposed sensor, and the results indicate that the sensor had superior urine glucose recognition. These results thus demonstrate that the noble nano-structured electrode with a high surface area and electrocatalytic activity offers great promise for use in urine glucose sensing applications.<\/jats:p>","DOI":"10.1038\/srep21009","type":"journal-article","created":{"date-parts":[[2016,2,15]],"date-time":"2016-02-15T10:33:30Z","timestamp":1455532410000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":53,"title":["Plain to point network reduced graphene oxide - activated carbon composites decorated with platinum nanoparticles for urine glucose detection"],"prefix":"10.1038","volume":"6","author":[{"given":"Mohammad Faruk","family":"Hossain","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae Y.","family":"Park","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2016,2,15]]},"reference":[{"key":"BFsrep21009_CR1","doi-asserted-by":"publisher","first-page":"453","DOI":"10.1002\/adfm.200901639","volume":"20","author":"S He","year":"2010","unstructured":"He, S. et al.
