文摘

The C-g-C3N4 possesses the better conductivity and solubility and was more favorable for chemical modification due to the existence of carboxyl group. The novel nanocomposite (C-g-C3N4-PEI) possessed excellent luminous efficiency and stability in S2O82− solution. Based on the C-g-C3N4-PEI-S2O82− ECL system and enzyme inhibition, the fabricated biosensor was developed for ultrasensitive detection of OPs.
