  Hybrid molecules and materials - HyMolMat

The research activities of the group are focused on the design, synthesis, and characterization of hybrid organic-inorganic compounds:

1. Metal complexes and molecular compounds are developed for applications in biomimetic catalysis and nanomedicine. Specifically, polyoxometalates (tungstates, molybdates, and vanadates) are functionalized with peptides or other organic moieties to confer recognition capabilities towards biological targets. Spectroscopic techniques (NMR, FT-IR, UV-vis, fluorimetry, circular dichroism), cyclic voltammetry, and dynamic light scattering are employed to investigate the behavior of these compounds in solution.

2. Composite materials incorporating nanomaterials (such as halloysite nanotubes, nanocellulose, and metal-organic frameworks) within polymeric matrices are developed. Whenever possible, starting materials are sourced from waste materials (e.g., textiles). These novel materials are functionalized with catalytic units to foster green chemical transformations. Electron microscopies (TEM, SEM), Thermal characterizations (TGA, DSC), surface analysis (XRD, Raman, Z-potential) are applied for their characterization, while HPLC, GC, NMR are used to monitor their activity.

Nanostructures are usually obtained by laser ablation of bulk solids under solvents. Plasmonic properties of metal nanoparticles are exploited in particular for the SERS (surface enhanced Raman scattering) effect, whereas the magnetic properties for magnetophoresis. Finite element based simulations are used to model the optical responses of complex nanostructured assemblies. For the nanobiotechnology field the SERS technique is used for applications like tumor cell targeting and identification, functionalizing plasmonic and magneto-plasmonic nanostructures with antibodies and engineered peptides. Nanobiotechnology, but also environmental applications are developed also using µfluidic devices to be integrated in new portable sensor technologies. Raman and SERS  nanostructures are exploited  also in cultural heritage studies for the identification of pigments, dyes, and other organic materials present in artworks.

• UV lamps Helios Italquartz 125 W and 400 W, for UV-activated reactions (e.g. polymerization processes);
• Sonicator Laborsonic P Sartorius Stedim ultrasonicator for the homogeneization of miniemulsions;
• Custom made spin, dip and spray coaters ror the deposition of inorganic and hybrid films and coatings;

The lab is also equipped with an ultrasonic spraying system that allows the fabrication of thin and uniform films for different applications. The spray gun can process both liquid and colloidal solutions creating micrometric drops on the surface. Furthermore, the deposition is performed in a dedicated climate chamber and, optionally, the sample can be heated up to 500 degrees by a precise titanium hotplate.
