Conducting polymers as transduction mechanisms in biomedical sensing platforms.

Conducting polymers (CPs) have been the subject of intense research since the ability of polyacetylene to conduct electricity was first discovered in the 1970s. Since then a wide variety of both organic and inorganic systems have been developed. Such materials have found extensive applications in the fields of electrochemical sensors, mechanical actuators, solar cells and flexible electronic displays. The incorporation of conducting polymers into such devices requires not only an understanding of the various charge transport mechanisms involved but also an ability to control these mechanisms in both bulk and nano-fibre form. In recent years advancements in screen printing and polymer processibility have increased the scope for biomedical sensors utilising conducting polymers as the transduction element. Increased understanding of the interaction between biological analytes and the conductivity mechanisms in these polymers has also contributed to these developments. This talk will highlight some of the author’s previous approaches to the incorporation of conducting polymers into biomedical sensing platforms as well his previous experience in the field. Important considerations required for the further advancement of electroactive materials to biomedical applications will also be discussed.
