ABSTRACT:
A magnetic particle and fabrication method thereof. The magnetic particle comprises a polymer core, a magnetic material layer covering the polymer core, and a silicon containing layer covering the magnetic material layer. In addition, the magnetic particle may further comprise a coupling agent on the silicon containing layer, and an active molecule connected to the coupling agent. The magnetic particles provide controllable size, uniform diameter distribution, high magnetization, improved storage stability, and modified surface for targeting biomolecules for biomaterial separation and environmental analysis.
