Influence of a charged graphene surface on the orientation and conformation of covalently attached oligonucleotides: a molecular dynamics study
Original language description
Molecular dynamics simulations of oligonucleotides anchored via an aliphatic linker to a graphene surface were performed in order to investigate the role of the surface charge density in the structure and orientation of attached DNA. Two types of interactions of DNA with the surface are crucial for the stabilisation of the DNA?surface system. Whereas for a surface with a zero or low positive charge density the dispersion forces between the base(s) and the surface dominate, the higher charge densities applied on the surface lead to a strong electrostatic interaction between the phosphate groups of DNA, the surface and the ions. A difference in the behaviour of the double stranded DNA and single stranded DNA was observed. The double stranded DNA interacts with the surface at low- and zero-charge densities exclusively by the nearest base pair, keeping its geometry close to the canonical B-DNA. The single stranded DNA, owing to its much higher flexibility, has a tendency to maximise the at
