Nonenzymatic amperometric dopamine sensor based on a carbon ceramic electrode of type SiO/C modified with CoO nanoparticles.

An amperometric nonenzymatic dopamine sensor has been developed. Cobalt oxide (CoO) nanoparticles were uniformly dispersed inside mesoporous SiO/C. A sol-gel process was used for the preparation of this mesoporous composite material (SiO/C).
