Abstract
Binding of yDNA bases with gold nanoclusters is studied using density functional theory. We find that gold complexes interact asymmetrically with y-bases. The binding energies in these complexes are found to lie between -29.1 and -77.1 Kcal/mol. The binding is contributed by direct Au-N or Au-O anchor bonds, as well as non conventional Au...H-N type of hydrogen bonding.
