  • Title: Single-stranded DNA adsorption on chiral molecule coated Au surface: a molecular dynamics study.
    Author: Liang H, Li Z, Yang J.
    Journal: Phys Chem Chem Phys; 2010 May 07; 12(17):4431-4. PubMed ID: 20407716.
    Abstract:
    All-atomistic molecular dynamics simulations with explicit water solution are performed to investigate the interaction between single-stranded DNA (ssDNA) molecules and chiral N-isobutyryl-cysteine (NIBC) molecule coated Au surfaces. Different contributions to the force exerted on ssDNA are analyzed. It turns out that the experimentally observed stereospecific adsorption behavior of ssDNA on d/l-NIBC self-assembled monolayer surface mainly originates from the interaction between the dipole moment of NIBC and the negative charge carried by ssDNA.
