Dr. Hafeli's research aims to improve drug targeting in cancer therapy. To do this, he is developing radioactive pharmaceuticals (= radiopharmaceuticals), determining their microdosimetry, and then delivering them to different organs and tumours. A particularly fascinating approach to deliver pharmaceuticals that his lab is investigating is magnetic drug targeting. For this purpose, magnetic nanoparticles and microspheres are made that can be physically targeted to cancer cells using magnetic fields.
