Abstract
Described herein is a magnetic particle, which includes a knobby copolymer core, a polymer layer, a magnetic substance layer and a silicon-based layer. The polymer layer covers the knobby copolymer core and has at least one functional group. In addition, the magnetic substance layer covers the polymer layer and the silicon-based layer covers the magnetic substance layer. Furthermore, a manufacturing method of the magnetic particle is also described.
