With this methodology, it is possible to diagnose illness, allergies, alimentary fraud, and even to detect small molecules such as toxins, pesticides, heavy metals, etc. For this reason, any procedures that improve the detection limit, sensitivity or reduce the analysis time could have an important

The elaboration of sensors to satisfy these needs is highly regarded [4][5]. Screen-printed electrodes on polymeric

Although the Basel, Rotterdam and Stockholm Conventions [4] have forbidden hazardous pesticides including MP, this pesticide is still used for many corps. MP and
