Incoherent Neutron Spin-Echo Spectroscopy as an Option to Study Long-Range Lipid Diffusion
Diffusion is the fundamental mechanism for lipids and other molecules to move in a membrane. It is an important process to consider in modelling the formation of membrane structures, such as rafts. Lipid diffusion is mainly studied by two different techniques: incoherent neutron scattering and fluorescence microscopy. Both techniques access distinctly different length scales. While neutron scattering measures diffusion over about 3 lipid diameters, microscopic techniques access motions ofdoi:10.1155/2013/439758 fatcat:aterursprjbrhmoaaf3b4jnhim
