1. NMR Investigations of Peptide-Membrane Interactions, Modulation of Peptide-Lipid Interaction as a Switch in Signaling across the Lipid Bilayer
Abstract : The complexity of multi cellular organisms demands systems that facilitate communicationbetween cells. The neurons in our brains for instance are specialized in this cell-cellcommunication. READ MORE

2. Membrane Induced Structure in Transmembrane Signaling Proteins and Peptides : Peptide–Lipid Interactions Studied by Spectroscopic Methods
Abstract : Biological membranes, defining the boundary of cells and eukaryotic organelles, are mainly composed of lipids and membrane proteins. Interactions between these lipids and proteins are needed to preserve the tight seal of the membrane, but also to induce structure for proper function in many membrane proteins. READ MORE

3. NMR diffusion studies on lyotropic liquid crystalline systems
Abstract : The pulsed field gradient fourier transform nuclear magnetic resonance (PFG-FTNMR) method to measure translational diffusion coefficients in multicomponent systems has been applied to amphiphilic molecules forming liquid crystalline phases.By analyzing the concentration dependence of the diffusion coefficients of water and amphiphile in a micellar system of N,N-dimethyldodecy lamine oxide (DDAO) in water it was possible to conclude that the micelles formed were polydisperse in size and shape.

4. Biological membrane interfaces involved in diseases : a biophysical study
Abstract : Interactions between peptides and biological lipid membranes play a crucial role in many cellular processes such as in the mechanism behind Alzheimer’s disease where amyloid-beta peptide (Abeta)is thought to be a key component. The initial step of binding between a surface active peptide and its target membrane or membrane receptor can involve a non specific electrostatic association where positively charged amino acid residues and a negatively charged membrane surface interact.

5. Peptide-Liposome Model Systems for Triggered Release
Abstract : Liposomes are widely used in drug delivery to improve drug efficacy and to reduce side effects. For liposome-encapsulated drugs to become bioavailable and provide a therapeutic effect they must be released, which typically is a slow process that primarily relies on passive diffusion, liposome rupture or endocytotic uptake.
