Packages of DNA strands containing silver, measuring just two or three nanometres in size. Leiden physicists Donny de Bruin and Dirk Bouwmeester create these packages, which can enter living cells on their own. They then activate the silver with light, causing the cells to break down. This could, in…

Stacked layers of graphene can act like a mirror for beams of electrons. Physicists Daniël Geelen and colleagues discovered this using a new type of electron microscope. In an article in Physical Review Letters, they describe their results, which could lead to the development of optics for electron…

The Digital Humanities and Cultural Analytics minor will be offered in the 2026 academic year, and replaces the 2025/2026 Digital Humanities and AI Minor.

Human cells are protecting their proteins from unfolding and aggregating. That's what biophysicist Alireza Mashaghi and his team discovered after seven years of in-depth research into the folding mechanisms of proteins. With an unprecedented approach, the team was able to study the folding of a single…

Thanks to a €4.8 million grant from the Dutch Research Council, a consortium that includes four physicists from Leiden University will develop a national facility for atomic-scale research into novel materials. This initiative is expected to drive innovation for energy transition.
