Dr. John Colleran is a lecturer in Chemistry at the Dublin Institute of Technology. He is active in both undergraduate and postgraduate level teaching, in the areas of polymer chemistry, chemical kinetics and electrochemistry. He is a member of the Applied Electrochemistry Group and his current research interests are focused on development and characterisation of composite materials for novel biological, inorganic and environmental applications. Within these applications, macro-, micro- and nano-electrodes are employed for sensing in biological and aqueous media.
Current work is focused on electrochemical determination of interactions of bioinorganic compounds with DNA. This research yields information on the binding mode, binding constants, DNA nuclease efficiency and radical identification and quantitation. Complementary to this work is the elucidation of mechanism and kinetics of redox reactions at DNA modified electrodes and electrochemical characterisation of bioinorganic compounds.
