Magnetic separation is an efficient separation technique in which CDs and iron oxide (Fe3 O 4) nanocrystals are utilized as doped material embedded in mesoporous silica beads. Silica microbeads are selected due to nano-sized pores, hydrophobic interactions with doped materials, and a large surface area.
