The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

De Microscopy Unit huisvest, onderhoudt en coördineert vrijwel alle microscopieapparatuur van het IBL. De beschikbare apparatuur varieert van conventionele licht- en fluorescentiemicroscopen tot confocale laser- en elektronenmicroscopen. Er is bovendien apparatuur beschikbaar voor histologie, met inbegrip…

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

Single-Molecule Microscopy (SMM) techniques constitute a group of powerful imaging tools that enable researchers to study the dynamic behavior of individual molecules.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

Traditional drug discovery approaches have been hampered by (in vitro) cell-culture models that poorly represent the situation in the human body.

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

In this thesis we investigated the ability of two-photon multifocal microscopy for single-molecule microscopy in live cells and organisms.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

This thesis described the development of novel scanning tunneling microscopy techniques to investigate strongly correlated electronic states in quantum matter.

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

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.

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

Het coronavirus heeft de wereld in zijn greep. Het vinden van een medicijn is nog nooit zo belangrijk geweest. Helaas zijn de ontwikkeling van nieuwe medicijnen en de ontwikkeling van een vaccin complexe, langdurige en vooral kostbare processen. Computermodellen kunnen dit proces versnellen. Wetenschappers…

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

Outflows are crucially important for the gas budget and evolution of luminous star-forming galaxies and AGNs, with observed mass outflow rates of the same order as the star formation rate. Greater star formation and black hole growth lead to more intense feedback and outflows, resulting in self-regulated…

Drug-induced liver injury (DILI) is one of the main reasons for drug attrition during pre-clinical and clinical phases of drug development as well as for drug withdrawal post-marketing.

This thesis aims to demonstrate how the achromatic nature and design flexibility of liquid-crystal optics can be used to improve high-contrast imaging instruments to facilitate detailed exoplanet characterization.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

This thesis examines silicon pore optics (SPO), a technology that exploits silicon wafers from the semiconductor industry to create extremely high quality X-ray optics, by studying its manufacturing process, applications, and prospects.
