Het doel van deze faciliteit is om het biomedisch onderzoek te versnellen door toegang te bieden tot geavanceerde licht- en elektronenmicroscopie en door het delen van expertise over monstervoorbereiding, beeldvormingsmodaliteiten, gegevensopslag en beeldanalyse.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

The dissertation describes TEM experiments on heterogeneous catalysts.

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.

In this thesis the combinatorial use of bioorthogonal labelling and Electron Microscopy (EM)-based imaging techniques is explored to enable observations of specific molecular targets in their ultrastructural context within the cell.

The research in this thesis is focused on tomographic reconstruction based on two imaging modalities in electron microscopy.

Bij electron nanoscopy worden enorme hoeveelheden data geproduceerd. Hoe kan data science helpen bij het verwerken en analyseren van al die data? Onderzoekers van LCDS, LIACS en NeCEN kwamen samen om dat te bespreken tijdens de 18e LCDS meeting.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

Triplet superconductivity refers to a condensate of equal-spin Cooper pairs (pairs of electrons with equal spin).

An objective of this research was to achieve direct, well-defined and non-rate-limiting electron transfer between respiratory enzymes and the electrode surface by means of 'Q-wires'.

Onderzoeksgroepen in het Quantum Matter & Optics onderzoeksprogramma onderzoeken elektronische eigenschappen van interacties van materie en lichtmaterie, met de nadruk op quantuminformatie.

Natuurkundige Daniël Geelen ontwikkelde tijdens zijn promotie een nieuwe microscoop die laag-energetische elektronen gebruikt. Zulke elektronen zijn minder schadelijk voor biologische en organische materialen. Geelen promoveert op 31 mei.
