Query: Structure and Dynamics of DNA-dendrimer complexation: Role of
  counterions, water and base pair sequence   We study sequence dependent complexation between oligonucleotides (single
strand DNA) and various generation ethylene diamine (EDA) cored poly amido
amide (PAMAM) dendrimers through atomistic molecular dynamics simulations
accompanied by free energy calculations and inherent structure determination.
Simulations reveal formation of a stable complex and provide a detailed
molecular level understanding of the structure and dynamics of such a
complexation. The reaction free energy surface in the initial stage is found to
be funnel-like with a significant barrier arising in the late stage due to the
occurrence of misfolded states of DNA. Complexation shows surprisingly strong
sensitivity to the ssDNA sequence which is found to arise from a competition
between enthalpic versus entropic rigidity of ssDNA.
