“…the signals, a series of modifiers/catalysts were used, including carbonaceous materials (multi-and single-walled carbon nanotubes, carbon microspheres, graphene, etc.) [31], conducting polymers [32,33], nanocomposites [34], metallophthalocyanines [35], and enzymes [36]. Screen-printed electrodes (SPEs) are widely used in various analytical chemistry applications such as biochemistry, medicine, pharmacy, environmental protection, and food science due to their low cost, ease of use, size reduction, lack of contamination, allowing at the same time the development of sensitive, accurate, and high-reproducibility sensors [21,31,37,38].…”
