Octahedral metal complexes chiral recognition

Finally a brief introduction to chiral recognition of DNA (a chiral biomolecule) by optically pure octahedral metal complexes will be presented. 

The principal question addressed, is there any kind of chiral recognition in electron transfer reactions involving GO or HRP and enantiomerically pure metal complexes. The chirality of optically active metal complexes may be different. Examples include central carbon chirality, when a complex has a side chain with an asymmetric sp3 carbon (Chart 2A), planar chirality as in the case of asymmetrically 1,2-substituted ferrocenes (Chart 2B,C), and central metal chirality when an octahedral central metal itself generates and enantiomers (Chart 2D) (202). These three types are discussed in this section.
