Peptide pores

Saturday 13 September 2008 11:10

Interaction between peptide pores in lipid bilayers The elucidation of lipid-mediated interaction forces between membrane proteins and the corresponding lateral distribution in the plane of the membrane is an important step towards a quantitative understanding of the functional mechanisms of membrane proteins and membrane peptides. Experimentally, the lateral structure and organization of multi-component membranes is as important as it is difficult to probe. In this work we show how the (...)

XPCS on lamellar phases

Saturday 13 September 2008 12:02

Dynamics of a lamellar phase studied by XPCS and dynamic light scattering X-ray Photon Correlation Spectroscopy (XPCS) is a relatively new technique, successfully used to study the dynamics of soft-matter systems. Conceptually, it is rather similar to the traditional Dynamic Light Scattering (DLS) technique, but its main advantages with respect to DLS are the potential of reaching much higher scattering wave vectors and the fact that it is less affected by multiple scattering. Smectic (...)
