King's College London and the UUÂãÁÄÖ±²¥ of Chemistry are pleased to present this one day academic symposium to celebrate the lifetime achievements of Professor Helmut Maecke who will be presented with the UUÂãÁÄÖ±²¥ Bequerel Medal. The Symposium will also celebrate the centenary of Marie Curie being awarded the Nobel Prize for Chemistry. The synthesis and application of peptide-chelate conjugates for labelling with radioactive metal isotopes, for medical imaging by gamma scintigraphy or positron emission tomography, and for anti-cancer therapy, has become a core activity in radiopharmaceutical design. This one day symposium provides an opportunity to hear from leading experts in these fields and to network with peers and colleagues.
