Sergio Murgia received the Ph.D. degree in 2002 at the University of Cagliari, Italy. Currently, he is an Assistant Professor in physical chemistry at the University of Cagliari. His scientific activity is mainly related to the field of colloids (e.g., micellar, microemulsion, emulsion, vesicle, and lyotropic liquid crystalline systems). Research interests mainly concern the physicochemical investigation of the nanostructure and the dynamic behavior, along with the evaluation of biological (e.g., cytotoxicity) and technological (e.g., drug release efficacy) features of innovative formulations based on self-assembled molecules. Given the interest of these systems in the pharmaceutical area, most of such formulations are engineered exploiting biocompatible surfactants (e.g., lipids and/or phospholipids). Particular emphasis is placed on self-assembled systems showing promising applications in the drug delivery field. Implications of dispersion (nonelectrostatic) forces in salt-containing colloidal systems are also qualitatively and quantitatively explored, as well as the interactions of ionic liquids with classical surfactants. Physicochemical studies are mainly conducted through NMR (relaxation and self-diffusion methods), SAXS, FT-IR, and cryo-TEM techniques.
