Physics, M.V. Lomonosov Moscow State University, Moscow, Russia 10.3762/bjnano.4.72 Abstract We report here a way for improving the stability of ultramicroelectrodes (UME) based on hexacyanoferrate-modified metals for the detection of hydrogen peroxide. The most stable sensors were obtained by
as sensors in scanning electrochemical microscopy (SECM) experiments for imaging of hydrogen peroxide evolution.

The detection
with a size of 25 μm and less. For such electrodes (ultramicroelectrodes, UME) the thickness of the diffusion layer is comparable to the diameter of the electrode resulting in enhanced mass transport in comparison to macroscopic electrodes and thus leading to improved sensitivity and detection limits
