Comparative Study on Biomimetically Synthesized Ferrofluid at different pH and Concentration

Abstract

Ferrofluid is a superparamagnetic nanofluid which is used in hyprthermia therapy for cancer treatment in which we injecting the ferrofluid on the vein of cancer patients. The rationale is based on a direct cell-killing effect at temperatures above 41–42˚C it should be mentioned that the heating potential is strongly dependent on the particle size and shape, and thus having well-defined synthetic routes able to produce uniform particles is essential for a rigorous control in temperature. medical diagnosis and therapy require the magnetic particles to be stable in water at neutral pH and physiological salinity. The colloi-dal stability of this fluid will depend first, on the dimensions of the particles, which should be sufficiently small so that precipitation due to gravitation forces can be avoided, and second on the charge and surface chemistry
