We are interested in the design of functional nanoparticles based on polymers. Inspired by nature, we combine synthetic polymers with nature's building blocks such as carbohydrates, peptides and proteins. We aim at combining the versatility of synthetic polymers with the bioactivity of building blocks found in nature. The aim is to create nanoparticles for the delivery of drugs. Our groups therefore work on the interface between polymer science, nanoparticle design and medicine.
