This NCCR Collaborative Project brings together three groups of the NCCR to develop new ideas for drug delivery inspired by Nature and better understand nanoparticle-cell interactions. The project is led by Profs. Stefan Salentinig (Module 3), Alke Fink (Module 3) and Frank Scheffold (Module 2), and aims to apply the know-how of the Scheffold group in optical manipulation of small particles to tackle important research questions in chemistry and bio-nanotechnology studied in the Salentinig and Fink labs.
