Abstract:
The present invention relates to polymer microgel beads having a polymeric matrix with nanomagnetic particles dispersed substantially uniformly therethrough, wherein a steric stabilizer is associated with the particles, the steric stabilizer being a polymeric material that (i) forms at least part of the polymeric matrix of the beads, and (ii) comprises a steric stabilizing polymeric segment and an anchoring polymeric segment, wherein the steric stabilizing polymeric segment is different from the anchoring polymeric segment, and wherein the anchoring polymeric segment has an affinity toward the surface of the nanomagnetic particles and secures the stabilizer to the particles.
