Key Points

Particle size distribution peaks around 100 nm were identified using dynamic light scattering.
Zeta potential and concentration data confirmed the particles' origin from polycondensation of silica.
Multi-angle dynamic light scattering provided clearer insights into particle growth in micro-regions of the water.
Colloidal silica particles increase in size and concentration with depth, forming larger aggregates around 500-600 nm.
