Analogues of Colloidal silicon dioxide occur in nature, and can be found in rocks, plants and animals. This is achieved by adhering to the surface, increasing the distance, and reducing attractive forces (van der Waals forces and electrostatic attraction decrease with increasing distance between the particles). Nonetheless, biological barriers can decrease the success of translating them for therapeutic applications since the media composition can induce their colloidal stability loss.
