In Microbial Sciences, we perform multidisciplinary research to understand the structure and function of microbes at all levels of biological organization, from small molecules and cellular structures at atomic resolution to multicellular communities.

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

Due to the modern techniques of combinatorial chemistry and high-throughput screening, data on the biological activity of many millions of compounds is known. However, it is still very difficult to transfer this data into knowledge: if we know that compounds A and B bind to a certain protein with high…

Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…

The Kroese-Duijsters Symposia aim to provide researchers from different fields and different career stages to meet in an informal setting, to stimulate discussions and to start new collaborations. The Kroese-Duijsters Symposia started in 2022 and we are pleased to invite you to the 3rd Kroese-Duijsters…

Research within our group revolves around the atomic structures of large bio-molecules and their complexes.

Unraveling the immune-suppressive actions of drugs like prednisone.

Electrolysis is a technique that can be used to convert CO2 into fuels and other useful products. To do this efficiently and on a large scale, however, we need to understand exactly how electrolysis works. Professor Marc Koper is an expert in this field.

Leiden physicist Milan Allan and his group have discovered an apparent paradox within a material that has zero electrical resistance. They measured trapped charges, while charges should in theory keep flowing in the absence of resistance. The discovery could provide a missing piece of one of the big…

In the research programme Microbial Sciences we perform state-of-the-art research in the field of biotechnology and microbial sciences.

Research at the THEOR group is comprised of the following research themes:

The research program of the QO group has three leading themes: Optical Physics, Quantum Optics, and Photon-Matter Interactions. We work mostly at the boundaries between these themes with entanglement as a bridging and binding agent.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

The focus of our theoretical physics research is the nature of macroscopic matter that is in one or the other way still in the grip of quantum physics.

This thesis focused on the exploration of monolayer graphene as a membrane in direct methanol fuel cell (DMFC) applications, with improvements achieved through plasma exposure or damage- free chemical functionalization.

The CIGR brings together a diverse range of unique expertise in genome research rooted in biology, chemistry and physics. Members of the CIGR investigate genome folding and genome transactions. An important aspect is direct as well as long term relevance for medicine. The available expertise extends…

The Joan van der Waals colloquium is an ongoing bi-weekly lecture series.

The "Van Marum Colloquia" are a collaborative lecture series between the LION and LIC institutes, focusing on fundamental and applied surface science.

Quantum computers deserve their own quantum internet. This is a network that dispatches information not in the form of bits - ones and zeros - but rather as qubits, just like in the quantum computer itself. In the view of Dirk Bouwmeester, a professor in Leiden’s Quantum Matter & Optics research group,…

The surface and the edges of graphene are expected to provide higher sensitivity and specificity in detecting and characterizing single molecules. However fundamental physical limits exist in reaching an ultimate precision in detecting the dynamics of chemical and biological systems. The research in…

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this population will result in an enormous increase in the demand for food, consumables, water…

Even a small quantum computer should be able to simulate exactly the properties and behaviour of new molecules. This would take chemistry to an entirely new level. Better solar panels, more powerful batteries, saving lots of energy in the chemical industry: the applications have the potential to transform…

By detecting the tiny forces between a micrometer sized magnet and the spins of hydrogen nuclei, we can do MRI with a volume resolution that is approximately 12 orders of magnitude better than a conventional MRI.  

MRFM combines the principles of magnetic resonance and atomic force microscopy.

The Physics and Quantum Matter and Optics specialisation is one of the two programmes Leiden offers in experimental physics. The programme can be tailored to individual needs and interests.

Research in this group, headed by Gerard van Westen, focusses on computational methods integrated in different parts of the drug discovery process. More specifically, topics include innovative treatments for cancer, selectivity modeling, translational research, allosteric modulation, drug resistance…

Coordination chemistry is the chemistry of metal atoms

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…

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Some species of proteins which can form liquid-like condensates, also exhibit growth into fibers (or fibrils). One particularly interesting set of such proteins are those that are associated with neurodegeneration in which the fiber growth may be related to the pathological fibrils observed in disea…

Brownian motion is the random motion of (colloidal) particles due to collisions with the atoms and molecules of the solvents, which are moving due to temperature.

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.
