| 7. | An Acetylcholinesterase biosensor based on graphene-gold nanocomposite and calcined layered double hydroxide Original Research Article Enzyme and Microbial Technology, Available online 17 February 2014, Pages Chen Zhai, Yemin Guo, Xia Sun, Yuhe Zheng, Xiangyou Wang
Graphical abstractThe CLDHs as enzyme immobilization matrix was applied to construct highly performance-enhanced AChE biosensor. Graphene-gold nanocomposite was dropped on the surface of the glassy carbon electrode, and greatly improved the conductivity of the modified electrode. Amperometric experiments were performed on a workstation by adopt a conventional three electrode system. The obtained biosensor based on enzyme inhibition for determination of pesticide showed a wide linear range and low detection limit.
