Functional Conjugated Polymers for Bio and Optoelectronic Applications


Jinsang Kim, University of Michigan

Conjugated polymers (CPs) have become emerging materials for many useful applications due to the tunability of their properties by variation of chemical structure. Particularly the biosensor application of CPs has gain much interest recently because CP-based sensors can provide large signal amplification. The concept, design principles, and applications of conjugated polymers for selfsignal amplifying biosensors and sensor arrays will be discussed. We have developed conjugated polymer-based biosensors to detect clinically important biological materials such as DNA and protein. Our signal amplifying sensors are designed to achieve high sensitivity by means of the energy harvesting property and highly emissive property of conjugated polymers. Receptors are rationally designed to provide specificity toward a target analyte to realize high selectivity. Signal amplifying DNA microarrays, PDA liposome arrays for selective potassium detection, prostate specific antigen sensors, bioconjugated emissive organic nanoparticles for immunofluorescence labeling, warfare agent detection sensors ill be discussed. Optoelectronic application is another promising direction of our conjugated polymer research. Flexible conjugated polymer photovoltaic cells having controlled nanostructures, pure organic phosphorescence emitters, and negative index materials will be also discussed in the second part of the talk.
