The Paul Scherrer Institute PSI is the largest research institute for natural and engineering sciences within Switzerland. We perform cutting-edge research in the fields of future technologies, energy and climate, health innovation and fundamentals of nature. By performing fundamental and applied research, we work on sustainable solutions for major challenges facing society, science and economy. PSI is committed to the training of future generations. Therefore, about one quarter of our staff are post-docs, post-graduates or apprentices. Altogether, PSI employs 2300 people.

The Center for Radiopharmaceutical Sciences (CRS) at Paul Scherrer Institute offers the entire spectrum of radiopharmaceutical sciences which includes radionuclide development (in close cooperation with PSI’s Laboratory of Radiochemistry), radiolabeling chemistry, lead-optimization, in vitro and in vivo assessment, preclinical nuclear imaging (PET and SPECT) and radionuclide therapy as well as translation of new and novel radiotracers for clinical studies (in collaboration with academic and industrial partners).

The Radionuclide Development Group as part of the CRS specializes in basic radiochemical research to produce unique radionuclides for radiopharmaceutical labelling purposes. This includes the design and development of new targetry systems and state-of-the-art isolation strategies to produce radionuclides with high specific activity and purity such that radiopharmaceuticals like folates, peptides and antibodies can be labelled in the attempt to use them as diagnostic or therapeutic medicines. The group provides radionuclides to the center towards preclinical and clinical research.
