Nanomaterials


At the NanoBioMedical Centre we design, characterize and functionalize large variety of NANOMATERIALS of different dimensions (OD, 1D, 2D and 3D) including:

  • metallic nanoparticles: Au, Ag, Cu;
  • metal oxides: ZnO, TiO2, CuO, Cu2O, Fe2O3, Fe3O4, Gd2O3;
  • phosphates:  hydroxyapatite and its derivatives;
  • quantum dots: Cu2O, CuInS/ZnS, GQDs, CQDs;
  • carbon nanomaterials: nanotubes, graphene, graphene oxide;
  • organic: cubosomes, liposomes, micelles, peptides, polydopamine spheres, dendrimers;
  • thin films: Heusler’s alloys, carbides, nitrides, iron oxide layers, TiO2, ZnO;
  • hybrid, hierarchical and porous: polydopamine coated magnetic Fe3O4 nanoparticles, MOFs,  MSNs, ZnO.
These nanomaterials are further given to the functionalization in order to ensure novel properties. To do so, we:
  • change the stability and improve the functionality of nanomaterials by tuning the hydrophobicity and surface charge,
  • combine the nanomaterials of different properties to form multimodal particles with many functions: such as fluorescence and magnetic imaging probes that can selectively deliver drug molecules,
  • develop new hybrid materials, built from at least two functional components, with new unique physicochemical and biological properties.
