Together with my team of enthusiastic students, we strive at understanding the fate of polymer nanoparticles in suspension. For this purpose, we are focusing on different aspects of this complex problem. On one hand, we study the physico-chemical characteristics of the polymer chains in, and on, the nanoparticle to gain a deeper fundamental understanding of the polymer behavior. And, on the other hand, we develop synthetic pathways to prepare polymer nanoparticles for targeted applications.
