Description	In present paper, composite polymer/nanoparticle microcapsules were designed, synthesized and characterized in detail. A temperature-sensitive polymer poly-N-isopropylacrylamide (PNIPAM) with a reversible volume response to external stimuli was chosen as a suitable material, hence the composite PNIPAM/silica and PNIPAM/Fe3O4 microcapsules were prepared. The presence of silica particles on the surface makes it possible to attach further functionality such as ligands for specific adhesion. Owing to the presence of iron oxide nanoparticles, it is possible to induce a macroscopic volume change of the capsules as well as their hydrophobic/hydrophilic properties remotely by exposing them to an external alternating magnetic field in the radiofrequency range (400 kHz).
