Electrochemical sensors screen-printing

An important aspect in the development of sensor technology is the need for mass-produced and low-cost disposable transducers [48]. This is especially relevant for environmental and biomedical analysis. For electrochemical sensors, screen-printed electrodes fulfill this need, and the ease of preparation and low cost of MIPs make them attractive as recognition elements for such devices. A first report on this topic demonstrated that an imprinted polymer could be coated onto screen-printed carbon electrodes, and the resulting devices could be used as an amperometric sensor [33]. 

Moreover, disposable electrochemical sensors for the detection of a specific sequence of DNA were realised by immobilising synthetic single-stranded oligonucleotides onto a graphite or a gold screen-printed electrode. Tire probes became hybridised with different concentrations of complementary sequences present in the sample.

Electrochemical sensors and biosensors offer the achievable opportunity of simplifying the analyses of complex matrices, outside of the laboratory, by suitable modification of appropriate electrode materials [1-5]. One of the most attractive methods for the fabrication of such devices involves the use of screen-printing technology. This allows the (bio)sensors to be manufactured in a wide range of geometries at low cost, particularly when carbon is used therefore, this allows the devices to become disposable [1,2]. A typical screen-printed electrode design commonly used in our laboratories for prototype investigations is shown in Fig. 23.1.
