A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

The nanoscale structure of a catalyst under reaction conditions determines its activity, selectivity, and stability. For the production of sustainable energy and materials, new catalysts are needed. By understanding the structure-activity relationships of catalysts under reaction conditions, insight…

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.  

Human and animal cells are very complex: very different chemical processes are going on at the same time, but they are separated from each other because the cells are divided in compartments. These compartments may also have a profound effect on the potential efficacy of therapeutics, because the drug…

In our lab, we investigate the physics and material properties of low-dimensional systems.

PURPOSE: In the present study we investigated the root-cause of an interference signal (100-200 nm) of sugar-containing solutions in dynamic light scattering (DLS) and nanoparticle tracking analysis (NTA) and its consequences for the analysis of particles in biopharmaceutical drug products.

Archaeometric analysis of glazed pottery assemblages from the Early Byzantine to the Early Modern periods in the Aegean.

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

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

Dr. Stephan Hacker, an assistant professor in the department of Molecular Physiology at the Leiden Institute of Chemistry of Leiden University has been elected secretary of the board of APNet, the Assistant Professor Network Netherlands. Hacker will take a leading role in the young network organisation…

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

The role of domestic and wild resource exploitation in Bronze Age subsistence

Graphene and other layered materials combine into completely new substances. Leiden physicists establish the ground rules for designing such materials by measuring how the layers in the stack interact. Publication on November 29 in Nature Communications.

An international team with researchers from Leiden revealed how a bacterium repurposed an internal system to control its movements. Movement control is very important in host invasion, which can lead to disease. Publication on 27 April in Nature Communications.
