摘要：

Polyelectrolyte brushes loaded with magnetic nanoparticles can be formed through the reaction of immobilized Fe2+/3+, ions in the brush. These particles show very unusual magnetic properties, not normally associated with such small nanoparticles. Upon application of all external magnetic field, the brushes showed reversible dimensional changes.
