High pressure studies on biological systems
The effects of hydrostatic pressureon biological samples are poorly explored. The temperature influences the thermal energy as well as other thermodynamical parameters including the volume and the effects are difficult to separate. Pressure is a thermodynamical variable which has so far not been used extensively to probe biological samples. It provides, in particular, a well adapted tool for the study of protein folding and dynamic energy landscapes and makes it possible to characterise thermodynamically complex biological systems. It can open access to intermediate states, which cannot be reached by temperature variation. The lack of research using pressure is due to technical challenges and experimental difficulties, especially in combination with neutron scattering. Thus we will further develop the high pressure equipment present at the ILL and apply it for milestone experiments.
