“…[9] Previous work by this group had used these types of screen-printed carbon electrodes as the basis of a biosensor using electrodeposited conducting PANI/PVS films onto which was deposited HRP or antibodies. The nature of these biosensors has been described elsewhere.…”

Screen-printing technology is widely used for the mass-production of disposable electrochemical sensors. The practical utility of carbon screen-printed electrodes has been exploited, despite the fact that little is known about the nature of the electrode reactions. (Wang, J.; Pedrero, M.; Sakslumd, H.; Hammerich, O.; Pingarron, J. Electrochemical activation of screenprinted carbon strips. The Analyst 1996, 121 (3), [345][346][347][348][349][350]. Given the complexity of carbon electrodes in general, and differences in the composition of commercial carbon inks, the question arises as to how such differences and complexity affect their electrochemical reactivity. The aim of this

“…Screen printing is usually carried out on alumina ceramic [9] or plastic, commonly polyester [21], polycarbonate [28] and polyvinyl chloride (PVC) [29] substrates. Ceramic substrates are commonly used with metal inks since ceramic can withstand the higher curing temperatures that these inks require, in contrast plastic substrates are mainly used with lower temperature carbon or polymer based metal inks.…”

“…Different ink compositions can be produced by either the addition or deposition of various substances such as; enzymes [14], polymers [18], and metals [19,20]. A major drawback with screen printing is that they are usually used in a batch system [14,21] and incorporating them into a flow system has always been a crucial challenge as the following criteria must be met: the cell needed be designed to incorporate (or allow the simple exchange) of the electrodes with good mechanical stability and precise alignment. It must also have a very small dead volume.…”

Hybrid Microfluidic Sensors Fabricated by Screen Printing and Injection Molding for Electrochemical and Electrochemiluminescence Detection

et al. 2009

An integrated microfluidic/electrochemical sensor with a dual working electrode configuration was fabricated for voltammetric and electrochemiluminescence (ECL) applications. The fabrication method integrates the two techniques of injection molding and screen printing for the first time. Injection molding is used to fabricate the flow cell with integrated electrical and fluidic connectors. Screen printing was used to print the electrodes directly onto the injection molded base plate. An over molding procedure followed by ultrasonic welding was used to form the complete sensor. The electrochemical and ECL performance of the sensors was assessed by applying different electrochemical methods such as cyclic voltammetry (CV), anodic stripping voltammetry (ASV) and chronoamperometry. The attractive analytical performance demonstrates good capability of the disposable sensors for routine online electrochemical and ECL measurements.

“…This result differs from those observed in previous works on screen- printed Au and Pt electrodes, in which the difference between anodic and cathodic peak potentials is greater than the expected for a reversible couple. The deviations from theoretical values are attributed to the binder in the ink composition covering some active sites of the electrodes [10,15]. To explain this behavior a model was developed by Amatore et al based on nonlinear diffusion effects due partial coverage [16].…”

Disposable Gold Electrode Array for Simultaneous Electrochemical Studies

et al. 2007

View full text Add to dashboard Cite

An efficient and inexpensive eight gold electrode array has been manufactured by a combination of screen printing and gold electrodeposition techniques. Gold electrodeposition was performed in potentiostatic and galvanostatic conditions. Different treatments, involving temperature and polishing control, led to electrodes with different roughness. The electrochemical behavior of the generated gold surface was studied by cyclic voltammetry showing the characteristic response of polycrystalline gold, in contrast with disposable gold electrodes fabricated by screen printing from gold inks. The electrodes were chemically modified through the adsorption of alkanethiols selfassembled monolayers and the coupling of a model protein. Both reactions were followed by cyclic voltammetry and Electrochemical Impedance Spectroscopy (EIS). The electrodes have shown high reproducibility in their electrochemical behavior as well as in their modifications.
