g-C3N4被发现具有内在的类似过氧化物酶的活性，并且可以通过H2O2催化氧化3,3',5,5'-四甲基联苯胺(TMB)，产生显色反应。利用 g-C3N4 过氧化物酶样催化活性和葡萄糖氧化酶 (GOx)，开发了一种用于血清样品中葡萄糖检测的比色方法。葡萄糖的线性范围为5至100μM(R-2=0.9987)，检测限低至1.0μM。该方法用于肉眼检测血清样品中的葡萄糖。 (C) 2014 Elsevier B.V. 保留所有权利。
g-C3N4 was found to possess intrinsic peroxidase-like activity, and could catalytically oxidize 3,3',5, 5'-tetramethylbenzidine (TMB) by H2O2 to produce a color reaction. Using g-C3N4 peroxidase-like catalytic activity and glucose oxidase (GOx), a colorimetric method for glucose detection in serum samples has been developed. The linear range for glucose was from 5 to 100 mu M (R-2=0.9987) and the limit of detection was as low as 1.0 mu M. The proposed method was applied to detect glucose in serum samples by the naked eyes. (C) 2014 Elsevier B.V. All rights reserved.
