Magnetic fluid refers to the highly uniform dispersion of magnetic nanoparticles in the carrier liquid after being coated or modified by surfactants to form a stable and functional colloidal solution. It is also known as ferromagnetic fluid. Namely，magnetic fluid is a stable colloidal liquid composed of magnetic solid particles with a diameter of nanometers, base carrier liquid (also called media) and interface active agent. This magnetic fluid has no magnetic attraction in a static state but exhibits magnetism when an external magnetic field is applied. Magnetic fluid is a new type of liquid functional material, which has both the magnetic properties of solid materials and the fluidity of liquid materials, 빛의 특별한 성질뿐만 아니라, heat, magnetism and so on.Therefore, it has high application value, and the application fields are mainly related to aerospace, 기계, 전자 제품, 에너지, 화학 산업, 야금, medical treatment, 등., and its application fields are constantly expanding. It can be employed in magnetic fluid sealing, 자성유체 윤활, 자성유체 댐퍼, 자성유체 연삭, 자성유체부양. After modifying the magnetic fluid and conferring it with different functional groups, it can be used in nucleic acid extraction, protein coupling, 화학발광, 셀 정렬, and immobilized enzyme.
