Nanomaterials (NMs) exhibit unique and fascinating properties due to the high surface area, quantum confinement as well as shape/size dependent properties, hence offering broad range of applications including nanoelectronics, environment, biomedical field, and energy. Properties and Functionality can be controlled and/or tuned upon the chemical composition, synthesis route and doping.
This paper will be devoted to three main topics: (i) effect of doping on structural, optical and magnetic properties of diluted magnetic semiconductors – DMSs (ZnO, CdO and MgO) NMs for spintronic devices; (ii) magnetic oxide NPs for theranostics; and (iii) nanotoxicology where selected commercial metal oxide NPs (ZnO, Fe3O4 and TiO2) as well Graphene Oxide (GO) will be assessed in terms of size and concentration against aquatic organisms. For better understanding and in-depth analysis of nanostructured materials’ properties and performance, band structure calculations based on density functional theory (DFT) will be presented.
