Magnetoviscous Effect of Magnetic Fluid Targeting Drug Delivery System

摘要：

The magnetic fluid (MF) viscosity in MF targeting drug delivery system isn’t constant.With the change magnetic field strength,MF viscosity will change due to MF magnetoviscous effect.The magnetoviscous effect mechanisms in low and high concentration MF are different and qualitatively analyzed respectively.Drop needle movement method under controlled temperature was adopted to measure magnetoviscous effect.Experiment results show the viscosity linearly increases by magnetic filed strength under low magnetic field.The viscosity reaches max value when MF is magnetic saturation.Through curve fitting,the magnetoviscous effect formula is got.Based on this formula,the MF viscosity in changed magnetic field can be obtained.The MF drug movement behave will be controlled by magnetic field and can be transferred accurately to target.This result also can be generalized to other MF viscosity research field.
