Abstract (en)
[origin: WO03035113A1] The invention relates to a magnetic dispersion based on water and/or dispersing agents mixable with water and nanoparticles dispersed and stabilized therein. The invention also relates to a method for the production of said magnetic dispersion. The invention has the aim of providing a magnetic dispersion having high saturation polarization with greater biocompatibility, the magnetic particles of said dispersion being suitable as transport vehicles for other pharmacologically and biologically active substances and a method for the production of said magnetic dispersion. According to the invention, the magnetic nanoparticles consist of magnetic core particles and an envelope of general formula M[Ap,C,Bq], wherein M are core particles, A are reactive groups, B are bioactive groups and C is cyclodextrine, consisting of 1,4-linked glucose units (C6H7O5)m[(3H)m-(p+q)], wherein m = 6 to 12, p is the number of A groups 1 to 3m and q is the number of B groups 3m-p.
