As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

The human body consists of hundreds, perhaps thousands of different types of cells, each with different morphologies and functions, despite having the same genome.

At Molecular Physiology we teach the following courses within the Leiden Institute of Chemistry's Chemistry and Life Science and Technology programmes.

This dissertation was to develop effective graphene-based nanofluidic devices by developing scalable fabrication methods and elucidating proton transport mechanisms.

This thesis focuses on developing wafer-scale two-dimensional (2D) materials by combining synthesis, transfer, characterization, and device integration of graphene, hexagonal boron nitride (h-BN), and BN-doped amorphous carbon.

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

The close interaction between organic chemi stry and biology goes back to the late 18th century, when the modern natural sciences began to take shape. After synthetic organic chemistry arose as a discipline, organic chemists almost immediately began to pursue the synthesis of naturally occurring compounds,…

Marine sponges are important members of reef ecosystems, as they play ecological roles that are essential for the health of the reef.

Biopolymer sequencing with graphene edge-based tunnel junctions has the potential to overcome current limitations with the third generation of sequencing based on biological nanopores.

Humanity stands at a pivotal juncture, facing the dual challenge of environmental sustainability and rapid population growth, projected to exceed 11 billion by century’s end.

We simulate interstellar clouds with special plasma expansions and chemical reactions on icy dust grains to be measured in ultra-high vacuum setups. This provides the data necessary to guide and interpret astronomical observations and to model reaction networks in space. [Harold Linnartz]

This thesis provides an overview of the development of the Pair Configuration to Molecular Activity Coefficient (PAC-MAC) model.

This thesis focuses on the design and synthesis of activity-based probes and inhibitors targeting enzymes involved in the degradation of specific plant glycans.

LED3 is the combined effort of three excellent institutes of Leiden University. Through joined hands, we are able to give rise to a more effective early drug discovery pipeline. Let us briefly introduce the three institutes.

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

Streptomyces bacteria are a valuable source of natural products, many of which are used in the clinic or in biotechnology.

To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

This thesis focuses on protoplanetary disks: flattened structures of gas and dust around young stars in which planets are expected to form and grow.

Vitamin A or retinol is essential in embryonic development, the visual cycle and the immune system.

The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

This thesis advances our understanding of lipid uptake, a vital first step in lipid metabolism, by developing innovative click chemistry-based tools to study how immune cells internalize lipids.

This Thesis shows discoveries in non-linear astrochemical kinetics as well as a deeper analysis of dark clouds chemistry.

To construct catalysts that can produce fuels from CO2 innumerable times, we need to learn much more about how catalysis works. Irene Groot is conducting groundbreaking research into catalysis at the atomic level.

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology components. We are developing hybrid systems, coupling light-harvesting nanoparticles to redox-enzymes (oxidoreductases)…

How can the combination of sound composition, astrochemistry, and epistemological analysis provide new and unexpected insights into interstellar chemical reactivity?

Originating from a collaboration between Leiden University, the Leiden University Medical Center, and the Technical University of Munich in 2021, the Virtual ChemBioTalks are an annual, half-day virtual event with world-leading speakers from all sub-disciplines of Chemical Biology.

Researchers at Leiden University have made a breakthrough in the study of the hereditary Pompe disease. Together with colleagues in York, they have developed a molecule that binds to the enzyme that is key to the progress of the disease. The findings have been published in ACS Central Science.

Many metalloenzymes that are key to bioenergetics are membrane enzymes, with canonical examples the complexes I, II, III and IV in the mitochondrial inner membrane. To study these enzymes in a native-like lipid membrane environment, we aim to develop novel bioelectrochemical techniques.
