چکیده انگلیسی:
Graphene modified glassy carbon electrodes have been developed for the determination of calcium dobesilate in pharmaceutical formulations. The prepared graphene and CNTs were used as a conductive substrate for electrochemical study of calcium dobesilate. The direct electrochemistry of calcium dobesilate showed a reversible cyclic voltammogram with a formal potential of 133 mV (vs. Ag/AgCl) for graphene modified electrodes in 0.1 M phosphate buffer. The linear concentration range of the sensor is 30-120 ng/mL for graphene modified electrode, respectively. The lifetime of biosensor is more than 2 weeks. The proposed modified electrode provides a new promising and alternative way to detect calcium dobesilate
