This laboratory focuses on photochemistry, photobiology and photo-medicine, in order to try to understand how light interacts with molecules, materials and tissues. Alongside, models are developed and tested in order to understand and predict phenomena subsequent to light absorption, covering a wide variety of processes such as molecular reactivity, the responses of the immune system, drug-delivery and gene therapy. A new technology was created - piezoporation - which is commercialized in the cosmetics market by the spin-off LaserLeap SA. In addition to applications in the medical field, the group encourages fundamental research, covering areas as diverse as theory of element chemical reactions or sources of climate change.
