The Institute for Bioscience and Biotechnology Research (IBBR) has entered into two separate collaborations involving its polyphosphazene (PPZ) polymer platform. PPZs are synthetic, biofunctional macromolecules with the potential to advance a wide range of biomedical capabilities. IBBR Fellow, Dr. Alexander Andrianov, is working with collaborators to develop new PPZs for use as coatings for medical devices and as carriers of medical imaging agents.
