A method for preparing silica nanoparticles, the method comprising: adding centrimonium bromide (CTAB) to a water and ethanol to create a first reaction mixture; adding NH4OH to the reaction mixture to create a second reaction mixture; adding a first amount of tetraethyl orthosilicate (TEOS) to the second reaction mixture to create a third reaction mixture; adding ethylenediaminetetraacetic acid (EDTA) to the third reaction mixture then adding a second amount of TEOS to create a fourth reaction mixture; obtaining formed silica spheres; separating the formed silica spheres; washing the formed silica spheres with water and ethanol; and drying the formed silica spheres in an oven for at least about 8 hours to obtain silica nanoparticles.
