Electronic structure studies of DNA-nanoclustersAuthors: Himanshu singh,Purshotam Sharma,Harjinder Singh Conference: Proceedings of the National Biennial Conference of Nanosciences and Nanotechnology Date: 2008-06-09 Report no: IIIT/TR/2008/18 AbstractThe synthesis of modified versions of DNA is an area that is receiving much attention because of their potential applications in biotechnology and nanotechnology. Recently, Eric Kool et al have re-engineered an expanded version of DNA by pairing size expanded x-bases with normal bases in a complementary manner, which they called as xDNA. xDNA bases are analogues of natural bases that are formed by insertion of benzene ring into the natural bases. Recently, there was arisen a huge interest in conducting properties of metal bound DNA structures. We use quantum chemistry methods to investigate the structural and electronic properties of x-bases and their interaction with gold atoms, in order to explore develop insight into the nature of binding between gold atoms and size expanded DNA.
