β-lactamase: a study of inhibitor susceptibility in various model systems
β-Lactamases are enzymes that can break down β-lactam substrates, such as antibiotics, preventing the use of these antibiotics for the treatment of various infectious diseases. However, some compounds, β-lactamase inhibitors, can block these enzymes allowing for possible treatments using a combination…

Leiden astronomers calculate genesis of Oort cloud in chronological order
A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly 100 billion comet-like objects, forms an enormous shell at the edge of our solar…

Nanoparticle – redox protein biohybrids
Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

The immune system: step it up or slow it down?
When foreign matter enters our body, our immune system has to make a choice whether or not to go on the attack. There are times when the system goes wrong, and we end up with an illness or an allergic reaction. Researchers at LUMC are trying to steer the immune system. The dossier on Immunity, Infection…
