Fig. 3From: Exploring the organic–inorganic interface in biosilica: atomistic modeling of polyamine and silica precursors aggregation behaviorHydrogen bond network between LCPA and phosphate ions. The interaction mechanism between LCPA and Phosphate ions is shown in detail; specifically, the positively charged amino groups ionically cross-link with the negatively charged oxygens of Pi\(^-\) (see black dotted lines). In addition, the hydrogen bond network among phosphates is also highlighted (red dotted lines)Back to article page
