The invention relates to a compound
drug carrier for multi-response mechanism and preparation method thereof. The compound
drug carrier achieves three types of response mechanisms, exogenous stimulus magnetic fields, heat and endogenous stimulus pH, to regulate
drug target release. The present invention provides a method to
control drugs to release fixed concentration quantity drug in the target area within certain time. The method solves the problem of drug or
medicine waste arising from traditional methods. The present invention alters the lowest solution temperature of
polymer liquids through regulating the structure of
molecular entity in the syntheses process of polymers. Through altering the temperature, the method regulates the physical characteristics of nanometer
drug carrier to control the release of drug targets. FePt nanometer granule wrapped by polymers alters the
polymer temperature through regulating the magnetic fields to cause the
polymer to have phase transformation, to achieve the purpose of controlling drug releases. The nanometer carrier has superior
cell compatibility,
high cell intake rate and low
cell toxic, and has wide application prospect in regulating the release of
drug target and treating
cancer diseases.
