The technology of screen-printed electrodes (SPEs) in biosensor development has received
much consideration. Their versatility, miniaturized size and the possibility of connecting them to portable
instrumentation make possible highly specific on-site determination of several drugs. This review highlights
the recently developed strategies toward immobilization of different biological molecules on disposable
electrodes for the sensitive and selective analysis of drugs. Thus, enzyme modified SPEs, DNA
modified SPEs and immunosensors based on SPEs are overviewed.
Keywords: Screen-printed electrodes, enzyme biosensors, affinity biosensors, drugs.
