Nanomagnetics in Biotechnology

Applications of nanomagnetic particles in cell separation and magnetic hyperthermia are presented here. In general, biological cells are weakly paramagnetic or diamagnetic. Therefore, to enhance the magnetic susceptibility of the biological cells to interact with an applied magnetic field, nano- to micron-sized magnetic particles are tagged to the biological cells. Nano-size magnetic particles are produced in-house for various bio-magnetic applications.
