This dissertation revolves around the design and implementation of novel instrumentation and related measurement techniques, at the single molecule level, for use in biophysical research. Chapter 1 presents an introduction to the field of fluorescence-based single molecule measurements. In particular,…

Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.

Bacteria have the ability to alter their morphology in order to adapt to changing environments.

This thesis comprises the development of reproducible synthesis procedures for two-dimensional materials (composed of boron, nitrogen and carbon) on different metallic surfaces.

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

There is an urgent need for more physiologically relevant cell culture methods to guide compound selection in pre-clinical stages of the drug development pipeline.

In condensed matter systems electron-electron interactions, negligible in everyday metals, can dramatically alter the electronic behavior of the system. Examples of such altered behavior include high-temperature superconductivity and modulation of the electron density.

On the 2nd of June 2021, students of the LL.M. European Law program and staff of the Europa Institute got together to ‘celebrate’ the end of teaching in the academic year 2020/2021.

This thesis focuses on using liposomes in two different treatment strategies; vaccination (or immunotherapy) and delivery of a small molecule, and in two different disease models; cancer and atherosclerosis.

With the powerful electron microscopes at NeCEN we study abnormalities in cells of blood vessels in cardiovascular disease, the interaction between pathogens and hosts in infectious diseases, molecular processes that cause cancer and the interaction between drugs and target proteins. Drug development…

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.
