In 2014, Tuček et al. assemble a review covering syntheses, physicochemical properties, and applications of hybrids composed of iron oxide nanoobjects (thin films, nanoparticles, etc.) with various carbon nanoallotropes including carbon nanotubes, graphene, fullerenes, quantum dots, etc. In particular, a special attention is devoted to hybrids of carbon nanotubes and rare forms (mesoporous carbon, nanofoam) with magnetic iron oxide carriers for advanced environmental technologies. The review also covers the huge application potential of graphene/iron oxide nanocomposites in the field of energy storage, biomedicine, and remediation of environment. Among various discussed medical applications, magnetic composites of zero-dimensional fullerenes and carbon dots are emphasized as promising candidates for complex theranostics and dual magneto-fluorescence imaging.
