Effect of double-stranded DNA on electrical double layer structure at oxide/electrolyte interface in classical molecular dynamics simulation

- The DNA dynamics at the SiO2/NaClaq interface can be calculated by the MD simulation.
- The adsorbed ionic charges at the SiO2/NaClaq interface affect the potential profile.
- The shielded DNA molecular charges do not affect the aqueous interfacial structure.
- The ionic behaviors at the biointerface can be elucidated by the simulation method.
- The simulation for a concentrated solution reflects a physiological condition.
