How are carbohydrates processed by the immune system? Can carbohydrates be used to trigger T-cells against other conjugated antigens? Can they be used as adjuvants?

PhD candidate Dennis Wander searches for the best of both worlds. That is to say: a cancer drug that is effective and also has minimal side effects. To this end, he makes new molecules inspired by two existing medicines. And not without result: ‘We have created a new variant that is very promising.’…

Which molecules go into forming planets? PhD candidate Christian Eistrup and his colleagues have created new models to research this question. Their findings could change our idea of which molecules were forming Jupiter or even Earth.

Quantum computing is an emerging technology, which holds the potential to simulate complex quantum systems beyond the reach of classical numerical methods.Despite recent formidable advancements in quantum hardware, constructing a quantum computer capable of performing useful calculations remains challenging.In…

Having a bachelor's, a master's and a PhD in Chemistry, Elena Sánchez López shifted to a more biological field of research for her postdoc. She completed all her studies at the University of Alcala, in Spain, before applying for a LEaDing fellowship at Leiden University, a Marie Sklodowska-Curie Cofund…

With great sadness we share the news that Prof. Harold Linnartz passed away suddenly and unexpectedly on Sunday 31 December 2023. We are all in shock, and our thoughts are with his wife and children, other family, and friends. Harold was at the heart of our institute, as a researcher, as a supervisor,…

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

Since May, Assistant professor BioTherapeutics Lu Su works in our faculty. Although she is still young, she already worked in many different fields and co-operated on two publications in big scientific journals. How did she become so successful and what motivates her to keep researching the possibilities…

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

Twenty years from now, the world population is estimated to be around 8.7 billion people, compared to the current 7.3 billion. In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables,…

On the occasion of the Women & Girls in Science Day, BBC Science Focus Magazine highlighted 6 prominent female chemists. Among them is Leiden professor Ewine van Dishoeck: 'Astrochemist investigating the building blocks of life'.

This thesis presents the first synthetic peptides ADP-ribosylated on serine, threonine, tyrosine, arginine and cysteine.

Cyclic peptides are investigated as a platform to induce different orientations between various ligands.

Before researchers can develop targeted drugs, they need to know exactly how a disease works. Biochemist Bert Beerkens created molecules that allow them to find out. He used caffeine as the basis for new molecules that enable research into certain receptor proteins on cells.

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

Three of the four Heineken Young Scientists Awards for 2022 have gone to researchers from Leiden: chronobiologist Laura Kervezee, physicist Jordi Tura i Brugués and health psychologist Liesbeth van Vliet.

The main goal of the research described in this thesis was the development of new photoactivated chemotherapy (PACT) ruthenium(II) complexes bearing a non-toxic photolabile ligand.

In the current global context, there is a pressing need to address sustainable energy supplies to safeguard our Planet and its ecosystems. The choices made by human society have a significant impact on genetic evolution and climate.

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

Although Sander Wezenberg just started working in Leiden in March this year, he already managed to win a Vidi grant from NWO. Inspired by nature, Wezenberg wants to bring synthetic molecules to life and teach them to communicate. But who exactly is Wezenberg and what drives him?
