of computational toxicology in hazard assessment of engineered nanomaterials
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…

Matter into context: population- and community-level impacts of nanomaterials in freshwater ecosystems
The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from…

Modelling the interactions of advanced micro- and nanoparticles with novel entities
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.

Photo-activation of ruthenium-decorated upconverting nanoparticles
Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

Nanoparticles: shapeshifters that pass along the food chain and end up in the brain
Nanomaterials can pass much further along the food chain than was previously thought. The particles can change shape and size in each organism, enabling them to pass on to the next one in the chain. Researchers from the Institute of Environmental Sciences discovered this accidentally when using a novel…

Nanotechnology promises to help farmers cut pesticide use – but could also make chemicals more toxic
Nanotechnology has pervaded numerous industrial sectors over the past decades. Although many of us may not be aware of it, nanomaterials are now embedded within many of the the products we use in our daily lives. The agricultural sector might be next in line. Leiden environmental scientists Tom Nederstigt…

Large-scale European project identifies risks of nanoparticles
The large-scale project NanoInformatics will assess the risks associated with nanoparticles. The project will be funded by the EU with 6.8 million euros and was launched at the beginning of this year. Three scientists from Leiden are involved. 'For the first time, this project combines the various experts…
