The project is aimed for development and functionalization of nanoparticles (NPs) based on technical lignins. Due to natural origin of lignin and good biocompatibility, lignin NPs (LigNPs) can find application as targeted drug delivery vehicles for future implementation in biomedicine. Within the scope of this project, we aim to develop novel multifunctional lignin nanoparticles from different lignin fractions and provide them magnetic functionalities, attach fluorescent probes, and investigate their drug loading capability.
