Ferrofluid for Domain Detection and Bio-medical Applications

Ferrotec’s water-based EMG Series ferrofluids are most often used for domain detection and bio-medical applications, and we offer an extended family of ferrofluid options with unique magnetic and particle properties to meet a broad range of requirements.

Domain Detection

Ferrotec’s water-based EMG series ferrofluids are extensively used for the study of magnetic domain structures in magnetic tapes, rigid and floppy disks, magneto-optical disks, crystalline and amorphous alloys, garnets, steels and geological rocks.

Bio-medical Applications

Ferrotec’s water-based EMG series magnetic nanoparticles may be incorporated into polymer microspheres (which are coated with antibodies and/or therapeutic/chemotherapy drugs), injected into tissues and then drawn to the site of a lesion using a strong magnetic field. They may also be used alone, as a medium for site-specific thermal ablation of malignant or necrotic tissue.
