Electrochemical sensors based on screen-printed electrodes (SPEs) are applied for the precise detection of an analyte concentration in a sample solution and is one of the thrust areas of research, especially in healthcare and environmental monitoring. In this article we report electrochemical characterization of some commercially available SPEs obtained from three different commercial manufacturers in three different redox probes such as potassium ferricyanide, ascorbic acid/vitamin-C and nicotinamide adenine dinucleotide. The main aim of this study is to compare the sensitivity, stability, ideality and reproducibility in the development of electrochemical sensors for specific detection of biological or chemical substances using SPEs.
