Bioelectrode materials have huge potential for use in neural prosthetic devices, such as the cochlear implant. Researchers have developed a gellan gum doped polypyrrole (conducting polymer) coating which enhanced the electrochemical properties of neural prosthetic electrodes. Gellan gum is a biologically derived polysaccharaide which has applications in tissue engineering and drug delivery.
