The imaging is based on using IrCl3 6 as the redox mediator to dissolve silver grains. The SECM probe is biased at a sufficient constant anodic potential (0.8 V vs. Ag QRE) to oxidize IrCl3 6 under diffusion control. SECM images of a patterned band array (2.8 mm 3 mm) and of an ‘‘EPFL” logo (8.6 mm 7 mm) have been recorded with a high resolution from the black-and-white negative photo films. The factors relevant to the quality of images are discussed.Scanning electrochemical microscopyElectrochemistrySilver halide photographyBlack-and-white negative photo filmtext::journal::journal article::research article
