Iron and its compounds show a huge potential in various nanotechnologies owing to their low-cost,
biocompatibility, non-toxicity, biodegradability, and environmentally friendly character. The broad
scale of accessible valence states (0, II, III, IV, V, VI) and polymorphism of iron(III) oxide [1]
contribute to the miscellaneous chemistry and quite unique portfolio of applications of Fe-bearing
nanomaterials. In particular, nanoscale zero valent iron (nZVI, Fe^0) is viewed as an
environmentally friendly tool for in-situ reductive treatment of ground water and surface water
contaminated by, e.g., chlorinated hydrocarbons, uranium, heavy metals, or cyanobacteria [e.g.
2,3]. Nanocrystalline iron oxides in various structural forms have been found promising materials
in biomedicine, biotechnologies, catalysis, photocatalysis of water or many magnetic applications.
The control of the structural, morphological and surface properties of nanocrystalline iron oxides
towards tailored applications in targeted drug delivery and MRI contrast enhancement, catalysis,
and direct solar splitting of water will be presented [e.g. 4,5].

Carbon is another biocompatible element playing a crucial role in current nanotechnologies also due
to the broad scale of various nanoallotropes including fullerene, nanodiamonds, nanotubes, carbon
dots or graphene. Among them, the wet chemical strategies towards non-covalent and covalent
functionalization of graphene and its derivatives will be discussed along with preparations,
properties and theranostic applications of carbon dots [e.g. 6,7].

The last part of the talk will be devoted to various multifunctional hybrids of iron/iron oxides
with carbon nanostructures and nanosilver with an emphasis on their applications in advanced water
treatment technologies, antimicrobial treatment, heterogeneous catalysis and biomedicine [e.g.
8-10].
