Studying lateral diffusion in lipid bilayers by combining a magic angle spinning NMR probe with a microimaging gradient system.
An alternative technique for studying the lateral diffusion in lipid membranes using pulsed field gradients in combination with magic angle spinning is presented. It is shown that MAS probes inserted in a microimaging device that produce high field gradients can be used to monitor also slow diffusion processes. As an example, measurements of the lateral diffusion of lipids embedded in the bilayer of a cubic phase are presented.
