Packages of DNA strands containing silver, measuring just two or three nanometres in size. Leiden physicists Donny de Bruin and Dirk Bouwmeester create these packages, which can enter living cells on their own. They then activate the silver with light, causing the cells to break down. This could, in…

Stacked layers of graphene can act like a mirror for beams of electrons. Physicists Daniël Geelen and colleagues discovered this using a new type of electron microscope. In an article in Physical Review Letters, they describe their results, which could lead to the development of optics for electron…

The Dutch Research School for Theoretical Physics (DRSTP) has received excellent ratings from an independent international committee. The DRSTP is a school for PhD training which has grown out of a collaboration between the theoretical physics departments at six Dutch universities—including Leiden—and…

Conferences, Workshops and Lectures showcasing research and tools in Digital Humanities.

Thanks to a €4.8 million grant from the Dutch Research Council, a consortium that includes four physicists from Leiden University will develop a national facility for atomic-scale research into novel materials. This initiative is expected to drive innovation for energy transition.

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

Physicists Carlo Beenakker and Jan Aarts have been elected Fellows of the American Physical Society. Carlo Beenakker: 'People acknowledge your contribution, that is just very good to hear.'

The Sackler Distinguished Lecture Series on Human Rights was established at Leiden University through an endowment given by Dr. Raymond R. Sackler and his wife, Beverly, international philanthropists with a commitment to supporting scientific research. The lectures mark the annual celebration of International…

Interested in how you can transfer your knowledge from yourself or from a knowledge institute into society at large? Several experts in the fields of grant development, Intellectual property rights and knowledge brokering take you through the various processes within four weeks time in this online c…

On 24 January 2025, a Workshop on ‘Protecting human rights through collective redress’ took place at the Central European University in Vienna. It was organised by Dr Zsolt Körtvélyesi in the framework of a Maria Skłodowska-Curie project on ‘Minority Rights – Towards Effective European Enforcement’.

To study how planetary systems come into existence we study much younger systems still in formation.

This thesis describes the Multi-site All-Sky CAmeRA (MASCARA), which consists of two small robotic telescope designed to detect exoplanets around the brightest stars in the sky.

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

This PhD-research is conducted to test the hypothesis that Gutenberg and consorts developed a standardised and even unitised system for the production of textura type, and that this system was extrapolated for the production of roman type in Renaissance Italy.

This dissertation revolves around the design and implementation of novel instrumentation and related measurement techniques, at the single molecule level, for use in biophysical research. Chapter 1 presents an introduction to the field of fluorescence-based single molecule measurements. In particular,…

In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).

In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.

The CMCB brings together a diverse range of unique expertise in microbial cell biology. Members of the CMCB investigate both model and non-model organisms, bacteria and archaea, pathogens and non-pathogens.

Inspired by natural photosynthesis, perovskite-based photoelectrochemical (PEC) systems are being developed for artificial photosynthesis, aiming to enhance solar-to-hydrogen conversion for green energy.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

There is an urgent need for more physiologically relevant cell culture methods to guide compound selection in pre-clinical stages of the drug development pipeline.

Research in the Jawerth lab focuses on using principles from soft condensed matter physics to understand important biological materials.

Develop EPR instrumentation and methodology to investigate intrinsically disordered proteins (IDPs).

Mechanobiology is a major area in biology, however, mechanics is currently a missing element in drug development pipelines. This has led to a high cost for the society. Mechanotoxicity of drugs often appears as a long-term side effect of drugs, and has led to removal of drugs from the market. Furthermore,…

This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

Nature publishes an article on a paradoxical discovery in superconductivity. Physicists are searching for superconductivity at high temperatures so that less cooling is needed in for example MRI machines. News & Views article by Prof. Jan Zaanen in the same issue of August 19th.

The Nobel Prize in Physics 2016 goes to David Thouless, Michael Kosterlitz and Duncan Haldane for theoretical discoveries in the field of topological materials. Haldane spent part of 2008 in Leiden; he is the 14th Lorentz Professor to win a Nobel Prize.

In the Netherlands, people probably grew up with De Fabeltjeskrant (a children’s show, ed.), but in France an introduction to fables plays a much more important role in a child's upbringing. PhD candidate Céline Zaepffel studied the role of fables in French education and teaching methods. It turns out…
