Electrochemical sensors are characterized by the simplicity of the device, low cost and high stability of a signal, and the possibility of their miniaturization. The high sensitivity is reached due to use as an electrode of the nanostructured surface, which will provide an increase in a surface area of an electrode. Another task is the selectivity of the electrochemical sensor in relation to a particular analyte in biological liquids of the complex structure. The selectivity of the sensing platform in relation to defined substances will be reached by the use of specific reagents (e.g. antibodies or aptamers) in the case of the definition of viruses and bacteria.
