Thank for your kind response.

However, I want to get the silca coated MNPs with the spherical shape. However, I got aggregated particles of silica coated MNPs via the protocol v1.2. Would you please let me know what is key factor to get spherical silica coated magnetic beads?

What results are expected  in the silica coated MNP synthesized by the protocol v1.2 and v1.3?

I got similar aggregated particles even when changing factors of ethanol purity (95%->99%) and mixing rpm (5005pm–>1000rpm).

Would you please let me know what is key factor to get spherical silica coated magnetic beads.

Best regards,
