In the last decade there were sustaining researches for developing new analytical devices, very sensitive and specific to some toxic compounds but also to control the quality of food. The electroanalytical techniques like cyclic voltammetry, square wave voltammetry, differential pulse voltammetry or stripping techniques and the use of composites electrodes allowed the detection of low concentrations of toxic compounds from different matrices. Our researches focused on the elaboration of new and inexpensive composite electrodes for the detection of heavy metals, but also the elaboration of new protocols for the estimation of antioxidant activity of some compounds or vegetal extracts.
