Active research

Lab of Biocompatible Polymers; Lab of Physical characterization and spectrophotometric analysis of chemical substances, Lab of Organic chemical processes, synthesis and purification of polymeric materials; Lab of characterization of biocompatible polymers; Lab of biological characterization of biomaterials and nanostructures

Services delivered under the right of third parties

For over twenty years, the Lab of Biocompatible Polymers conducts research concerning the synthesis, the physico-chemical characterization and, more recently, the preliminary biological characterization of biocompatible polymeric materials employed in the field of controlled release of biologically active substances (drugs, genes, proteins) and in the field of tissue engineering.

Moreover the laboratory has experience on lipid and phospholipid (lipid nanoparticles and liposomes) and oligosaccharide derived materials (cyclodextrins). The high formulation versatility of prepared and characterized systems allows their use also in the diagnostic, cosmetic and agricultural and food field. 

Then, this laboratory has experience on the chemistry of natural (eg polysaccharides, peptides, proteins) and synthetic polymers (polyaminoacids, polyesters, polyamides, polyanhydrides), on the most advanced procedures for the functionalization of such materials and on the technological processes that allow their transformation into systems whose sizes range from the nanoscale (nanoparticles, Nanogels, surfactants and polymeric micelles, interpolyelectrolitic complexes with DNA), to microparticles, to hydrogels (biodegradable, stimulus sensitive, intelligent), and to three-dimensional scaffolds for cell growth (films, sponges, fibrillar scaffolds).

The lab already undertakes research on commission of private companies in the production and characterization of systems for drug delivery and tissue regeneration. Some of these systems are already in the scale-up for an upcoming release in market. The Laboratory has highly specialized staff and a large equipment and it is able to interact with a large number of people working in the technological-pharmaceutical, biomedical,  diagnostic, cosmetic, agricultural and food fields.

 

Therefore the Laboratory is able to provide consulting service and research focused on the technological transfer to companies and research institutes both public and private, for the formulation and characterization of both innovative and conventional systems.
