Learning outcomes
The course aims to provide students with the theoretical and experimental tools for the preparation, study, development and application of nanomaterials in the fields of Biotechnology and Green Chemistry, for industrial, agro-food and biomedical applications. Properly activated and functionalized inorganic based nanomaterials with specific properties, such as diagnostics and sensorial, energy conversion and storage, transport of materials or substances, catalytic activity for production processes and transformation of resources, will be considered, in a perspective of sustainability development. The course also includes some laboratory experiences to provide practical manual skills as well as complementary competences to further refine the critical and analytical abilities for an optimal design, preparation, chemico-physical characterization and application of functional inorganic based nanomaterials in the fields of Biotechnology and Green Chemistry
Program

Noble metal nanoparticles and their plasmonic properties. Oxide based nanomaterials for photocatalysis. Magnetic nanoparticles. Organic-inorganic nanocomposites.
Multifunctional nanostructures activated by external stimuli for diagnostics, drug delivery and for curative treatments in nanomedicine.
Synthesis of nanoparticles in solution using "green chemistry" methods (coprecipitation, sol-gel, solvothermal, inverse micelles and ionic liquids). Microwave assisted synthesis. Strategies for obtaining different morphologies (nanorods, core@shell), porosity and size.
Surface functionalization of inorganic nanoparticles.
Chemical-physical characterization of nanostructures (structural, morphological, colloidal analysis). Spectroscopic investigation in ultraviolet, visible and infrared on luminescent nanoparticles. Investigation of the vibrational properties of the nanoparticles with infrared spectroscopy.
LABORATORY EXPERIENCES
1) Synthesis of metal nanostructures (Au, Ag) in solution and their spectroscopic characterization in the optical region (UV and visible). Study of the colloidal properties.
2) Preparation of TiO2 and Fe3O4 nanoparticles in solution with a microwave assisted reaction. Study of the colloidal properties. Structural analysis by X-ray diffraction.
3) Preparation of CaF2 and SrF2 nanoparticles functionalized with luminescent lanthanide ions in aqueous solution and their coating with a silica shell using the sol-gel technique. Chemico-physical characterization (structural, morphological, colloidal) of the nanoparticles. Study of their emission properties in the visible upon laser excitation in the near infrared region.
Bibliography
Examination Methods
The oral examination will include the exposition of a bibliographic paper on a subject of the Course and questions on the topics of the Course about the theoretical part as well as the examples, exercises and laboratory experiences. Particular attention will be devoted as well to the knowledge of the the concepts, methods, experimental setups and techniques used in laboratory experiences.
For both attending and not attending students the oral examination will cover all the topics discussed in the theoretical part, in the examples and exercises as well as in the laboratory experiences.
Written reports about the the laboratory experiences are required, describing the principles, the used experimental methods and the results obtained during the lab experiences. The reports have to be loaded to the Moodle platform as soon as the lab experiences will be completed.
