Plants, algae and cyanobacteria have the amazing capacity to perform delicate photophysical and photochemical processes of light capture, excitation transfer, charge separation and catalysis in fluctuating living environments. As a consequence, photosynthetic proteins and membranes form dynamic architectures.…

Adenosine diphosphate ribosylation (ADP-ribosylation) is a fascinating post-translational modification (PTM) that plays a role in a variety of cellular processes and is associated with several diseases, including cancer and viral infections.

In the Catalysis and Surface Chemistry group, we investigate how catalysis works on the molecular level. The group is divided in six subgroups, focusing on different aspects of heterogeneous catalysis, homogeneous catalysis and electrocatalysis.

If idioms employed in codes of conduct could be as idiosyncratic as examples suggest, then to what extent did early modern language of vice, too, persist in this genre?

A collaboration of physicists and chemists organized the LEELIS conference on new computer chip technology in Amsterdam on 10-11 November. Leiden physicist Joost Frenken is director of the organizing institute ARCNL.

A flu virus could cause a pandemic. And then we would be poorly armed because flu viruses are starting to become resistant to flu medications like Tamiflu. Chemist Merijn Vriends successfully worked on an improved version of such medications. He will be awarded his doctorate on September 12th.

Dying from viral infection due to organ failure and blood loss: we still know little about how it can happen. Among other things, Huaqi Tang developed an organ-on-a-chip to figure it out. 'These technologies can offer unprecedented opportunities to fight the viruses that threaten our society.' Tang…

How did dynastic organization – that it, the employment of non-ruling family members and the development of dynastic traditions and concepts – influence state formation in both Catholic Europe and Muslim West-Asia?

Edwin Bakker, invited speaker, at The EU conference on the future of higher education on March 9, 2016, advocated in his presentation ‘MOOCs as drivers of change: The teacher’s perspective’ for an open and positive attitude to digital learning environments and to leverage the potential of technolog…

On 11 December 2025, students and staff members from many fields of study had the opportunity to take part in a day-long workshop on the role of the senses in ancient religions.

On April 19, Pax Initiative, a youth led NGO, held its first ever event at the Museon in the Hague. The event, “International Court of Justice Idealab: The Future of the ICJ” was a productive and inspiring discussion among students and young professionals on how the Court can reach the 16th Sustainable…

In the studies described in this study, we introduce a novel ex vivo human skin barrier repair model. To develop this, we removed the upper layer of the skin, the stratum corneum (SC) by a reproducible cyanoacrylate stripping technique.

On September 30, 2022, our esteemed former colleague Gerrit Lodder passed away from the effects of Parkinson's disease. He leaves behind his wife Adry, his sons Gert-Jan and Michiel, his daughters-in-law Annerieke and Manyana and grandchildren Annelot and Gijs in sadness, but also in the knowledge that…

Specific fatty acid-sugar molecules allow leprosy bacteria, among others, to hide from our immune system. How exactly is not entirely clear. Hessel van Dijk, who received his PhD on 13 October, replicated the molecules, helping to solve a piece of the puzzle. Van Dijk's dissertation is titled: Synthesis…

Sander van Kasteren only noticed some small, subtle changes since he was appointed professor on 1 May. Still, he has to get used to the idea, even though he had been working towards the professorship for a few years. ‘I don't quite see myself as a professor yet.'

PhD candidate Marc Baggelaar of the Leiden Institute of Chemistry (LIC) graduated cum laude on Thursday 6 April. His thesis on the endocannabinoid system in the brain is very comprehensive and of high quality, according to the jury. ‘A very talented young scientist, that definitely belongs to the top…

An interdisciplinary team of Leiden researchers has discovered that wasting syndrome, a severe byproduct of tuberculosis, is the same for all humans and animals studied. The discovery offers new opportunities to investigate the still insufficiently understood condition. The scientists also developed…

Improving healthcare with our scientific discoveries: that is the goal of pharmaceutical research at Leiden University. And there’s a lot involved in that. Our research starts with the discovery of the effect achieved by a particular substance, and sometimes continues all the way through to the development…

How can we understand the material instability of photographic (mixed media) artworks (1960s - present) from an integrated approach of Art History, Conservation Science and Chemistry in order to preserve these works for the future?

The European Research Council (ERC) has awarded chemist Dr Alexander Kros a Starting Independent Researcher Grant of 1.4 million euro. He will be using the grant to study how molecules penetrate the natural barrier of a cell membrane. If his research is successful, it will in time bring about a revolution…

Destroying proteins from the Golgi apparatus of the cell in a controlled manner. That is the focus of chemist Marta Artola’s pioneering research. By developing a groundbreaking technology to target specific proteins in the Golgi, Artola aims to unlock new ways for drug development. For this ambitious…
