Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

At the moment, over 350.000 chemicals are registered worldwide for production and use. Their application, however, may harm human health and the environment.

Human skin equivalents (HSEs) can be a valuable tool to study aspects of human skin, including the skin barrier, or to perform chemical or toxicological screenings.

The aim of this project was to estimate emissions from lead products-in-use for the past, the present and the future and assess the development of toxicological risks associated with these products.

Engineered nanomaterials (ENMs) are widely used, and nanotechnological innovations grow with rapid pace. Studies on nanotoxicology have demonstrated that chemical toxicology as well as particle toxicology should be accounted for in predicting the safety of ENMs.

Zebrafish is an excellent model organism for studying various human diseases. Due to opaqueness of the adult phase, in vivo studies are restricted to early embryonic stages. This raises the need for rapid sensitive and non-invasive in vivo imaging methods to follow developmental processes, not only…

Ecotox is located in an ambitious surrounding at the Leiden University. It is an initiative of both institutes Institute of Environmental Sciences (CML) and Institute of Biology Leiden (IBL).

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

The Pharmacy research group focusses on the development of predictive models to improve clinical drug efficacy and safety. We are moreover strongly involved in the Master specialisation of Pharmacy at Leiden University. We work on clinical problems that require further mechanistic understanding and…

An international research consortium led by Bob van de Water, Professor of Toxicology at Leiden University, has been awarded a prestigious Horizon2020 grant of 30 million euros.

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

In this project, we aim to develop mathematical models to mechanistically and quantitatively predict the dynamics of cellular stress pathway activation and its relation with toxic effects when cells are exposed to various toxicants.

What is the mechanism of action preceding a physiological effects induced by metallic nanoparticles?

The master’s specialisation Bio-Pharmaceutical Sciences and Science Communication & Society at Leiden University is a two-year programme which combines research training in chemistry with one in techniques of communication.

The master’s programme of Bio-Pharmaceutical Sciences at Leiden University examines the research area of bio-pharmaceutical sciences and drug research. It offers seven specialisations ranging from BioTherapeutics to Industrial Pharmacy.

The master’s specialisation Industrial Pharmacy at Leiden University examines safety and quality control in the production of medicinal products, and prepares students for a career in Quality Assurance and Quality Control in the biotechnological and pharmaceutical industry.

The world is becoming clogged with plastic, with tiny plastic particles found everywhere, from the oceans’ depths to the mountain tops, soil, plants, animals and even inside us. The question is: what harm, if any, are they causing? In a new article on The Conversation, environmental scientists Meiru…

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.

Doctors and pharmacists should take greater account of obesity when dosing medicines. The distribution in the body and the breakdown of a medicine can vary considerably in obese patients. This is stated by clinical pharmacologist Catherijne Knibbe in the Annual Review of Pharmacology and Toxicology.

Toxys, Leiden University and Leiden University Medical Center have agreed immediately to commercialise and also develop further the ToxProfiler technology invented at the two institutions. ToxProfiler allows for rapid toxicity hazard identification of novel and existing drugs, chemicals, and other substances.…
