PhD thesis project: Immobilized enzyme microreactors in drug metabolism researchThe field of metabolism research would greatly benefit from the implementation of enzyme assays on immobilized enzyme microreactors. Most importantly, the use of flow conditions would allow for the spatiotemporal control of reaction parameters on demand by simply altering the chemical composition of the flow. However, immobilization of membrane-bound enzymes, which constitute the majority of enzymes responsible for human drug metabolism, has proven difficult, as the current immobilization approaches are not feasible for membrane proteins or result in unwanted alterations in enzyme function.The main goals of my thesis were twofold: (1) to develop a novel immobilization approach suitable for the immobilization of membrane-bound enzymes, without detrimental effects on enzyme activity or enzyme kinetics, and (2) to establish a microreactor platform for the study of drug metabolism in flow conditions. A central part of the thesis was also the utilization and characterization of a novel class of polymers, off-stoichiometric thiol-enes (OSTE), chosen for both their facile surface modification, and the ability to generate material-induced hypoxia.The thesis project resulted in 3 peer-reviewed articles, dissemination of results in 6 international conferences and 1 invention disclosure. The microreactor technology developed in the thesis project is now widely utilized within the research group and its commercialization is currently investigated in a Business Finland –funded project.Thesis available online: https://helda.helsinki.fi/handle/10138/324276
