Graphite-like carbon nitrides as peroxidase mimetics and their applications to glucose detection.
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 μM (R(2)=0.9987) and the limit of detection was as low as 1.0 μM. The proposed method was applied to detect glucose in serum samples by the naked eyes.
