Functieomschrijving

Medical radioisotopes are of paramount importance in diagnosing and treating various diseases. For this reason, a continuous, reliable and sufficient supply of such radioisotopes is required. Currently, the purification of radioisotopes consists of long, multi-step processes that contribute to a significant loss of product by natural decay.

Our innovative approach is to develop a microfluidic chip, based on liquid-liquid extraction, that significantly speeds up the purification step. Microfluidic liquid-liquid extraction has been investigated extensively for various chemical applications, but the application to a radioactive environment and to components specific to radioisotope production pose new challenges. First, radiation impacts the microfluidic chip materials and the chemical compounds required by the extraction step. Second, the transport of species, the related (radio)chemistry and the dynamical behaviour of the interface between both liquids in such a microfluidic system are not known yet. Third, it is unknown how to integrate such a system in a cyclotron or nuclear reactor.

We are looking for two candidate PhD-students who will investigate and develop such an innovative system. These PhD students will work in their own discipline and will act as a team at the same time, because all those disciplines are required to develop this technology.

PhD 1: A theoretical and numerical study to optimize isotope purification on microfluidic chips and the coupling to online irradiations facilities. Keywords: micro fluid dynamics, physical transport phenomena, liquid-liquid extraction, radiation transport (neutrons, gammas, …), lattice Boltzmann methods for fluid mechanics and radiation (Monte-Carlo)

PhD 2: Experimental study to develop chemical purification methods for medical radioisotopes in microfluidic chips and integrate the developed setup in a cyclotron. Keywords: radiometals, microfluidic liquid-liquid extraction, nuclear chemistry, inorganic and coordination chemistry, cyclotron production

This project is funded by NWO TTW and supported by NRG, URENCO, TRIUMF and UMCG.
