The growth of PMO cubes on nanoparticles with different outer surface area. a–c TEM images of the multipods Fe3O4@SiO2@RF&PMOs nanocomposites with controllable number of mesoporous PMO cubes by tuning the diameter of Fe3O4@SiO2@RF substrate nanoparticles: a 230 nm, b 200 nm and c 160 nm; d The linear fitting of the number of PMO cubes of the multipods Fe3O4@SiO2@RF&PMOs nanoparticles versus single particle surface area of the initial Fe3O4@SiO2@RF nanoparticles; e–h TEM images of the Fe3O4@mRF nanoparticles with different diameters (e, 200 nm; g, 300 nm) and the obtained corresponding multipods structured Fe3O4@mRF&PMOs nanoparticles f, h. Insets are 3D structural models of the multi-pods Fe3O4@SiO2@RF&PMOs nanoparticles, Fe3O4@mRF nanoparticles and multi-pods Fe3O4@mRF&PMOs nanoparticles. Scale bars represent 200 nm in b, e, g and 500 nm in a, c, f, h. The bars represent mean ± s.d. derived from n = 10 randomly selected nanospheres.
