Nanoparticles for biomedicinal applications
- drug delivery,
- diagnosis (e.g. as contrast agents in MRI),
- theragnostic applications (i.e. combining therapy and diagnosis).
We deal mainly with nanoparticles based on metal-organic frameworks (MOFs). MOFs are network solids in which inorganic nodes (clusters or metal ions) are linked via organic ligands in an infinite array. They are porous materials and these pores can be used to encapsulate various molecules including drugs and diagnostic agents.
