The use of silica–maghemite nanocomposites in magnetic refrigerators or various catalytic reactions has now been given a boost by the simple synthesis of maghemite nanoparticles that are supported on silicon oxide. The composition of the magnetic particles on the surface can easily be varied and it is shown that the particles are highly dispersed (see Figure).
