BIOCOMPATIBLE SUSPENSION STABILIZER FOR DISPERSING INORGANIC NANOPARTICLES INTO AQUEOUS SOLUTION

摘要

The present invention relates to a suspension stabilizer for dispersing inorganic nanoparticles into aqueous medium. More particularly, the present invention is directed to a biocompatible suspension stabilizer which comprises phosphoryl domain having an affinity to the surface of an inorganic nanoparticle and poly(ethylene glycol) having an affinity to the aqueous medium, and which is prepared by reacting a biocompatible poly(ethylene glycol )-derivati zed polymer with phosphine oxide having a leaving group.
