Mechanical and Chemical Protection of a Wired Enzyme Oxygen Cathode by a Cubic Phase Lyotropic Liquid Crystal

摘要: When implanted in animals, enzyme-containing battery electrodes, biofuel cell and biosensors are often damaged by components of the biological environment. An O2 cathode, superior to classical platinum which would be implanted, as part a caseless physiological pH miniature Zn−O2 or membraneless glucose−O2 cell, is rapidly serum urate at its operating potential. The cathode made electrically connecting, wiring, reaction centers bilirubin oxidase carbon with an electron-conducting redox hydrogel. In 7.3 electrolyte should operate at, positive of, 0.3 V (Ag/AgCl), where anion, common component, electrooxidized. Because unidentified electrooxidation intermediate, formed presence O2, damages wired electrocatalyst, must excluded from cathode. Unlike permeates t...
