Professor Richard Keen at James Cook University,
in collaboration with groups in Canberra, Sydeny and San Diego, has
been utilising NMR to study the binding of ruthenium metal complexes
to polynucleotides such as DNA. 'The ability to study larger segments
of DNA using the 900 is greatly enhancing our understanding of how
to design drugs that target specific genes'.
Another collaborative program involving co-workers at Canterbury,
NZ and Evanston, USA, is examining the process of electron charge
transfer in metal complexes, a phenomenon that is fundamental to the
function of many nanomaterials (light-activated eveices, catalysts)
and important metalloenzymes.
