My research focuses on the synthesis and chemical modification of biopolymers and biomaterials through homogeneous and heterogeneous catalysis to obtain smart biomaterials, whose chemical, physical, and biochemical properties can be changed in response to an external stimulus such as temperature, pH, light, or contact with biomolecules (proteins, enzymes, DNA, or RNA). These smart biomaterials are used in the manufacture of smart medical devices, in the formulation and assembly of liposomal systems as testing platforms for pharmaceuticals and biomarkers discovery, in the synthesis of core-shell nanopolymers coated by cell membranes or target materials, in the synthesis of functionalized 3D scaffolds, and in biosensor and bioimaging applications. Furthermore, I work with 3D bioprinting technology for the biofabrication of new mimetics and biological constructs layer-by-layer, and for the manufacture of 3D microfluidics systems to provide an ideal testing platform for drug discovery and target validation that allow the elucidation of physiological interactions, (organ-on-a-chip or human-on-a-chip), under dynamic experimental conditions.
