Recent developments in the field of screen-printed electrodes and their related applications

The development of analytical methods that respond to the growing need to perform rapid 'in situ' analyses shows disposable screen-printed electrodes (SPEs) as an alternative to the traditional electrodes. This review presents recent developments in the electrochemical application of disposable screen-printed sensors, according to the types of materials used to modify the working electrode. Therefore, unmodified SPE, film-modified SPE, enzyme-modified SPE and antigen/antibody-modified SPE are described. Applications are included where available. (C) 2007 Elsevier B.V All rights reserved.
