Scanning electron microscopy images of particles prepared and particle size analysis. In (a), the ballability of Fe₃O₄@SiO₂@p(GMA) was good and the average size was 90 nm. In (b), SEM micrographs of PLC-Fe₃O₄@SiO₂@p(GMA) also had a good ballability and the average particle size was about 105 nm. The average particle size of Fe₃O₄@SiO₂@p(GMA) was 96.70 ± 1.00 nm, and the particle size distribution range was 55 to 255 nm. For PLC-Fe₃O₄@SiO₂@p(GMA), the average particle size was 99.86 ± 0.80 nm and 90% of the particles were in the range of 58 to 295 nm. (a) Fe₃O₄@SiO₂@p(GMA). (b) PLC-Fe₃O₄@SiO₂@p(GMA).
