Gold nanorods are biocompatible nanoparticles that present an excellent two-photon signal that can be used to get high spatial resolution inside living cells. Gold nanorods are photostable and therefore can be followed inside cells for long time, with possible applications as trackers in live cells.

Multi-Angle Dynamic Light Scattering (MADLS) is a technique that is used to determine properties of particles in suspension. The measurements give the hydrodynamic size distribution of individual particles as well as particle clusters, and assists in the interpretation of the stability of the particles…

The legitimacy and justice of political institutions and arrangements are among the perennial and defining subjects of the field of political theory. Political theorists who participate in the research cluster ‘Legitimacy and Justice’ engage in both systematic and historical reflection on the ways legitimacy…

Cognitive processes of learning with a focus on reading comprehension and the development of mathematical skills.

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

The map application includes information from old and new buildings archaeological projects. This makes it possible to investigate whether water facilities (wells, cisterns) and waste facilities (cesspits, sewers) were the privilege of Leiden’s wealthy elite in the late 16th and 17th centuries or whether…

How did galaxies form? How did galaxies evolve?

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

Biologists today have to be able to work with big data. Data analysis skills should be taught from the start of the degree programme, or - even better - in secondary school. This is the message of Vera van Noort, new Professor of Computational Biology. Inaugural lecture 22 January.

The project MiCRop receives 20.3 million euros from the Gravitation programme of the Dutch Research Council (NWO). MiCRop will unravel the microbial community around crops. This knowledge will help to develop more sustainable crops that require fewer fertilizers and pesticides. Leiden professors Jos…

Ewa Snaar-Jagalska, Shuning He and colleagues from IBL, LION and LACDR reported on a new zebrafish study to understand micrometastasis of human cancer cells. They discovered a novel role for neutrophils in assisting metastasis formation, which provides critical insights for anti-cancer therapies.

Recently, NWO has decided to grant two interdisciplinary research proposals for national and international consortia submitted by researchers from the Institute of Biology Leiden. One of the proposals is led by Prof. dr. Ariane Briegel, the other one by dr. Remko Offringa.

How can novel bioimaging technologies and vertebrate model species be used to gain a better understanding of early cellular behaviours with the ultimate goal to increase our understanding of human development and disease processes?

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

What can we learn from how maritime conflicts were managed in the past? What significance did Maritime Conflict Management have in shaping the standards of diplomacy and international law in pre-modern Atlantic Europe (1200-1600)?

Making all those things we normally cannot see visible is the challenge that fascinates Fons Verbeek, Leiden's new Professor of Computational Bio-Imaging. Contributions from chemistry, optics and in particular computational sciences to making and processing these images give greater insight into the…

The Dutch universities as a whole are lobbying for a 'normal' academic year from the end of August, where on-campus teaching will be possible. It's a view that Leiden University shares. Rector Hester Bijl talks about what teaching will be like then. She also looks back on a year of lockdown.

Transplantation of labial salivary glands to the eyelids for patients with dry eye appears to give excellent results clinically.

High resolution altitude data created by airborne LiDAR allow the investigation of large areas and often inaccessible tracts of land and has the potential to reveal undiscovered archaeological heritage.

What Determines Perceptions of Bias toward the International Criminal Court? Evidence from Kenya. In this article, published on the website SAGE Journals in the Journal of Conflict Resolution, the authors Geoff Dancy, Yvonne Marie Dutton, Tessa Alleblas, Eamon Aloyo examine the attitude towards international…

Can we develop a generic method for Quan/Qual analysis of small molecule drugs, their metabolites and endogenous metabolites in (pre-)clinical samples?

Heritage Quest is a citizen science project in which volunteers help archaeologists in the quest for undiscovered archaeological heritage.

The aim of this study is to specify the strategic function of stance adverbs when qualifying a standpoint in an argumentative discussion.
