Abstract	Explicit molecular dynamics simulations were applied to a pair of amorphous silica nanoparticles in aqueous solution, of diameter 3.6 nm and four different background electrolyte concentrations, to extract the mean force acting between the pair of silica nanoparticles. Dependences of the interparticle forces with separation and the background electrolyte concentration were demonstrated. The nature of the interaction of the counterions with charged silica surface sites (deprotonated silanols) was investigated. Dependences of the interparticle potential of mean forces with separation and the background electrolyte concentration for the were demonstrated. The hydrophilic/hydrophobic nature of silica was demonstrated.
