Cells have developed several signaling pathways and transcriptional regulatory networks to regulate their size and coordinate their growth with the cell division....

This thesis is focused on force measurements applied to single RNA alone or associated with a protein. One of the biggest challenges arising when studying RNA comes...

Nanomaterials raise new questions in environmental and human toxicology and represent a novel interface with specific properties with the biological medium. Several...

Protein synthesis is a central mechanism of cellular life and understanding it is a challenge in biomedical research. Single molecule studies permit each reactive...

As observed for most stresses, tree frost resistance can be split into two main processes: avoidance and tolerance. Avoidance of freezing is achieved by introducing...

We have determined by grazing incidence X-ray scattering the interaction potential between two lipid bilayers, one adsorbed on a solid surface and the other floating...
