Cucurbit[6]uril/PVC-based semipermeable membranes as electrode modifiers for electrochemical investigation of insoluble substrates

We have described here a new kind of membrane material which acts as an ionic conductor on the surface of modified electrodes. Using these membranes it is possible to assemble highly efficient modified electrodes for electrochemical investigation of insoluble substrates. These materials can easily replace carbon paste electrodes and Nafion® for this purpose with a series of advantages.
