Printed thick-film biosensors
K.C. Honeychurch, University of the West of England, UK
The present review focuses on the thick-film electrochemical biosensors fabricated using screen-printing technology over the Past four years. Biosensors are composed of a biological recognition element acting as a receptor and a transducer, which converts the resulting biological activity into a measurable signal. A number of different transducers have been employed, but one of the most popular and successful is that manufactured by thick-film technologies such as screen-printing. These offer a number of advantages, such as economy, bio-compatibility and the possibility of miniaturisation, therefore allowing for the production of disposable ...
