Main components of the simulation a Long-chain polyamine (LCPA) containing 11 amino groups with a protonation degree of \(+9\). The two uncharged amino groups are highlighted with a blue triangle; b neutral disilicic acid (dimer|\({{\hbox {Si}}_2{\hbox {O}}_7{\hbox {H}}_6}\)), neutral cyclo tetrasilicic acid (tetramer|\({{\hbox {Si}}_4{\hbox {O}}_{12}{\hbox {H}}_8}\)), and negatively charged octahydroxyoctasilsequioxane-ion (octamer|\({{\hbox {Si}}_8{\hbox {O}}_{20}{\hbox {H}}_7^-}\)); c randomly generated amorphous silica nanoparticles
