The Polymer Functionalization Group, FUPOL, belongs to the Instituto de Ciencia y Tecnología de Polímeros (ICTP) del Consejo Superior de Investigaciones Científicas (CSIC). It is dedicated to the development of new methodologies for chemical modification of polymer materials that give rise to technological and/or biomedical advances that may be beneficial to society. To this end, he uses his experience in organic synthesis, polymer chemistry and biological evaluation of materials, and carries out his work in collaboration with different complementary groups.
