Collective dynamics in phospholipid bilayers investigated by inelastic neutron scattering: Exploring the dynamics of biological membranes with neutrons (2007)

Rheinstädter, M. C., Ollinger, C., Fragneto, G., Salditt, T.

We present the first inelastic neutron scattering study of the short wavelength dynamics in a phospholipid bilayer. We show that inelastic neutron scattering using a triple-axis spectrometer at the...

Collective Dynamics of Lipid Membranes studied by Inelastic Neutron Scattering (2007)

Rheinstädter, M. C., Ollinger, C., Demmel, F., Fragneto, G., Salditt, T.

We have studied the collective short wavelength dynamics in deuterated DMPC bilayers by inelastic neutron scattering. The corresponding dispersion relation $\hbar\omega$(Q) is presented for the gel...

Structure and stability of DPPE planar bilayers (2007)

Stidder, B., Fragneto, G., Roser, S. J.

Biomembrane mimics in the form of supported planar bilayers allow the application of a wide range of surface and interface analytical techniques. The structure and phase-behavior of single and double...

Composition of supported model membranes determined by neutron reflection (2005)

Vacklin, H. P., Tiberg, F., Fragneto, G., Thomas, R. K.

We have investigated the formation of supported bilayers by coadsorption of dipalmitoyl phosphatidylcholine (DPPC) with the nonionic surfactant P-D-dodecyl maltoside. The adsorption of mixed...

Phospholipase A(2) hydrolysis of supported phospholipid bilayers: A neutron reflectivity and ellipsornetry study (2005)

Vacklin, H. P., Tiberg, F., Fragneto, G., Thomas, R. K.

We have investigated the phospholipase A(2) catalyzed hydrolysis of supported phospholipid bilayers using neutron reflection and ellipsometry. At the hydrophilic silica-water interface, hydrolysis of...

Effect of low amounts of cholesterol on the swelling behavior of floating bilayers (2005)

Stidder, B., Fragneto, G., Roser, S. J.

The effect of the addition of 1, 2,4, and 6 mol % cholesterol to 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) floating bilayers has been investigated by neutron reflectivity. All samples...

Cholesterol induced suppression of large swelling of water layer in phosphocholine floating bilayers (2005)

Stidder, B., Fragneto, G., Cubitt, R., Hughes, A. V., Roser, S. J.

The effect of the addition of 10 mol % cholesterol to 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) floating bilayers has been investigated by means of neutron reflectivity measurements. The...
