Abstract
Described herein is a manufacturing method of a magnetic particle. First, deionized water, an organic solvent, a hydrophilic polymer, a lipid-soluble initiator, and at least two monomers are placed in a reactor and then stirred for polymerizing the at least two monomers into a copolymer to form a knobby copolymer core. Next, a polymer layer is formed to cover the knobby copolymer core, wherein the polymer layer has at least one functional group. Thereafter, a magnetic substance precursor is adsorbed by the knobby copolymer core covered with the polymer layer to form a magnetic substance layer. Further, a silicon-based layer may be additionally formed to cover the magnetic substance layer.
