Recent trends in electrochemical sensors for multianalyte detection - A review.

Voltammetric methods for screening compounds of varied interests are reviewed on the basis of the types of electrodes and analytical strategies. The scope of conventional voltammetric method has been considerably expanded in the last years due to the development of a plethora of modified electrodes, in particular, those involving nanocomposites. Voltammetric methods have distinct advantages over other existing methods regarding sensitivity, minimum detectability, applicability to biological samples without any pretreatment and time saving. Simultaneous determination of compounds by voltammetry offers the advantages of being economical and less time consuming as more than one analyte can be detected easily on the fabricated sensor at the same time. Present review article focuses on the simultaneous voltammetric detection of various compounds reported during the last five years.
