Encapsulation of nanoparticles with multifunctional, cross-linkable diblock copolymers for biomedicine

Schmidtke C., Ostermann J., Tran H., Pöselt E., Kloust H., Niehaus J., Becker S., Kreuziger A., Werner K., Pietsch A., Weller H., University of Hamburg, DE

We would like to present a micellular encapsulation method for nanoparticles (quantum dots, iron oxides, gold) which is based on a ligand exchange procedure of native ligands with a prepolymer poly(isoprene)-diethylentriamine (PI-N3) and subsequent ligand [...]

Water-soluble nanoparticles as an universal imaging tool

Niehaus J., Becker S., Schmidtke C., Ness D., Werner K., Weller H., Center for Applied Nanotechnology, DE

Here we present a two step concept for phase transfer of NPs soluble in non-polar media. The first step is an exchange of the stabilizing organic molecules against a multidental binding short chain polymer. In [...]
