    "abstract": "DNA base-gold interactions are studied theoretically at the DFT level using\nAu3 and Au4 clusters as simple catalytic models for Au particles. The bonding\nbetween DNA bases and gold clusters occurs via the anchoring of a Au atom to\nthe N or O atoms of the bases. In the most stable planar base-Au3 complexes,\nthe Au-N or Au-O anchor bonds are reinforced by N-H...Au bonds. The mechanism\nof formation of these nonconventional H-bonds is discussed.",
