Electrostatic deposition of polycations and polyanions onto cysteine monolayers.


Electrochemical impedance spectroscopy and the quartz crystal microbalance are used to monitor the deposition of polyelectrolytes onto an interface modified with a monolayer of cysteine. When using an anionic redox probe, Fe(CN)(6)(-4), the impedance of the cysteine modified electrode is a function of the solution pH; the charge-transfer resistance being… (More)
