The type-IV secretion system (T4SS) is a machinery able to transfer DNA and proteins between bacteria and in certain cases also to eukaryotic cells.

We investigate how radiation pressure can be used to influence the mechanical motion of a micro-mirror suspended from springs.

De Universiteit Leiden en de stad Den Haag werken nauw samen om de impact van ons onderzoek en onderwijs te vergroten en zo maximaal bij te dragen aan de ontwikkeling van de stad.

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

This thesis describes the synthesis, analysis of various tetrazine bearing compounds and use in bioorthogonal chemistry.

It has been a long-standing mystery how complex biological structures emerge from such seemingly uncoordinated building blocks as cells and tissues, in the presence of only minimal environmental guidance.

This doctoral thesis is an effort to understand how lipid phase-separation induced by diacylglycerol analogues in lipid-based nanoparticles affects their in vivo behavior, leading to specific nanoparticle-protein communications and selective cell targeting.

This thesis develops a method for direction dependent calibration of the ionosphere in radio interferometric data.

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

In this thesis, we developed new ways to use a technique called electroextraction (EE) to extract charged molecules from one liquid into another using an electric field.

In this work the reconstruction of a tau neutrino signal in the KM3NeT detector is discussed.

Metabolomics has the potential to play a pivotal role in understanding disease onset and progression, and ultimately personalized treatments. One of its major challenges is its large-scale implementation, which is necessary to deal with the high variability of the metabolome. In this work we have developed…

This thesis describes the importance of being able to control the selectivity of potential drug candidates.

N-acylethanolamines (NAEs), including N-arachidonoylethanolamine (anandamide, AEA), N-palmitoylethanolamine (PEA) and N-oleoylethanolamine (OEA), are signaling lipids that play an important role in different physiological process.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

The research described in this thesis centered on retaining exo-β-glucosidases implicated in health and disease, in particular the human inherited lysosomal storage disorder, Gaucher disease (GD).

This dissertation explores how Large Language Models (LLMs) can effectively and responsibly contribute to complex decision-making processes. By combining AI and human intelligence, Hybrid Intelligence (HI) emerges, allowing the strengths of both humans and machines to be utilized.

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.

Climate change is one of the largest challenges faced by humanity. To combat this research into alternatives to fossil fuels is ongoing. Dihydrogen is considered a good alternative fuel, since its burning only forms water.

Continuous optimization is never easy: the exact solution is always a luxury demand and the theory of it is not always analytical and elegant.
