Electrochemistry through glass
Glass is widely used as an electrical insulator in electrodes, but in spite of its high resistance, 100-nm-thick layers of glass have now been shown to be sufficiently conductive for electrochemical measurements. Obtaining redox couples through glass-covered nanoelectrodes suggests that the pH response of the glass is due to the formation of a hydrogel layer in acidic solution.
