In this talk we will review recent progress on nanoengineering of inorganic and carbon nanomaterials for tailored applications. Special emphasis is paid in the group to exploit the synergies of both types of materials by the preparation of nanohybrids with novel or enhanced properties. We will mainly focus on the development of nanomaterials for application in the biomedical field, but we will also highlight work performed in other areas such as the isolation and template assisted-growth of rolled-up single-layered 2D materials.

Among the different types of carbon nanomaterials, one advantage of using nanotubes is that their inner cavity can be filled with a chosen payload while the outer surface can be modified with biomolecules. The encapsulation of materials allows ultrasensitive imaging and even mapping of subcellular organelles, whereas functionalisation of the external walls of these filled carbon nanotubes (CNTs) allows targeting of cancer cells. We have also recently developed CNTs for dual imaging by radio-labelling iron oxide decorating the external surface of CNTs. The resulting hybrids allow single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRI). Worth noting is the enhancement of the MRI signal by modification of the nanocarrier (non-MRI active) rather than the magnetic nanoparticles themselves. The formation of such hybrid systems is not limited to the biomedical field. A large deal of attention is being devoted towards the isolation and growth of single layers of a wide variety of inorganic materials which is of interest for both fundamental research and advanced applications. We have reported on a versatile approach that allows the formation of single-layered inorganic nanotubes.
