Inorganic Chemistry Catalysis

Inorganic/organometallic chemistry. Sánchez-Delgado's current research interests are the discovery of novel metal-based drugs against tropical diseases (malaria, Chagas and leishmaniasis) and cancer, and the development of new catalysts derived from transition metal complexes or nano-particles for reactions related to the production of cleaner fossil fuels or improved biofuels.
