  • Title: In situ polymerization of highly dispersed polypyrrole on reduced graphite oxide for dopamine detection.
    Author: Qian T, Yu C, Wu S, Shen J.
    Journal: Biosens Bioelectron; 2013 Dec 15; 50():157-60. PubMed ID: 23850782.
    Abstract:
    A composite consisting of reduced graphite oxide and highly dispersed polypyrrole nanospheres was synthesized by a straightforward technique, by in situ chemical oxidative polymerization. The novel polypyrrole nanospheres can prevent the aggregation of reduced graphite oxide sheets by electrostatic repulsive interaction, and enhance their electrochemical properties in the nano-molar measurement of dopamine in biological systems with a linear range of 1-8000 nM and a detection limit as low as 0.3 nM.
