SYNTHESIS OF POLYSACCHARIDE COVERED SUPERPARAMAGNETIC OXIDE COLLOIDS

摘要

A kind of synthesis colloid includes that superparamagnetic metal oxide is coated with polymer, and the metal salt and polymer of acid solution can be cooled, then be neutralized, pass through the basis of control addition cooling solution, and it then converts, by heating, to homogeneous superparamagnetic metal oxide colloid. According to preferred embodiment, which can be polysaccharide. In another embodiment of the present invention, which can be glucan and metal salt can be ferrous salt and molysite, generate, and according to the method for the present invention, have extended blood plasma ray to superparamagnetic iron oxide colloid.
