This communication introduces a quick and easy method to modify a typical disk electrode's surface geometry. The method involves masking fragments of the flat surface of the working electrode, by applying a specific thin layer of chemically stable insulating material, leaving unvarnished, electrochemically active surface. Desired shapes are achieved by using a properly laser-engraved stainless-steel plate and a stamper to transfer the profiled varnish from the steel plate to the surface of the electrode. Three shapes - microdisk, microband, and ring electrodes - were applied to a platinum disk electrode, validated through optical and scanning electrochemical microscopies, and cyclic voltammetry. The first report on a new method of modifying surface geometry of disk electrodes.Part of the receptor layer is selectively blocking a with an insulating material.User-friendly, fast and inexpensive method.Possibility of obtaining a huge variety of unusual shapes from one disk electrode.A wide range of possibilities for further development.
