The differences in formal potentials of different metal hexacyanometalates is the basis of tuning the redox properties of PCMs by synthesis of mixed solutions, as far as that is possible due to the ion radii. Examples for a continuous tuning of the hexacyanoferrate redox potential are mixed nickel/iron hexacyanoferrates [30], mixed copper/iron hexacyanoferrates [56], and mixed cadmium/iron hexacyanoferrates [33].

Iron hexacyanoferrate (Prussian blue) [11,21-26] is inexpensive, and can effectively reduce the required operating potential to around 0 V, resulting in a minimal risk of interference. The main disadvantages of... 

An example of a transfer function based on a physical model is the Nemst impedance of a transport controlled electrode reaction. The impedance spectra in Fig. 7-14, which were obtained on a rotating platinum disk electrode at the equilibrium potential of the iron hexacyanoferrate redox system, exhibit the typical shape of a transport-controlled process. The transfer function cannot be described by a limited number of electrical circuit elements but must be derived from the differential equations of Fick s 2nd law and the appropriate boundary conditions. For finite linear diffusion, the so-called Nemst impedance Z can be derived theoretically...

Li et al. used the same approach for locally depositing and visualizing microarrays of copper hexacyanoferrate and iron hexacyanoferrate on glassy carbon electrode, respectively. Dissolution of a sacrificial Cu UME and stripping of Ee predeposited on a platinum UME generated relevant metal cations in the gap between the UME and the GCE, which precipitated some EefCNjs" anions that were generated simultaneously by reduction of EefCNjs" at the GCE. The deposited metal hexacyanoferrate microstructures showed catalytic activity for the oxidation of dopamine and the reduction of hydrogen peroxide, respectively, which were characterized by SECM.
