4. Collective dynamics in model biological membranes measured by neutron spin echo spectroscopy
Kelley, Elizabeth G. / Butler, Paul D. / Nagao, Michihiro
Cell membranes are extraordinarily heterogeneous environments composed of many thousands of chemically distinct lipids, sterols, and proteins. It is this very complexity and diversity in membrane composition that allows for its many varied and critical biological functions. These membranes are rather thin, only 3 to 5 nm thick, and present both structural and dynamic features on a wide variety of length and timescales. Within the hierarchy of length and timescales, the membrane’s mechanical properties control many of the key functions such as bilayer shape transformations, protein binding, budding, and molecular transport which in turn are related to such things as apoptosis, endocytosis, protein signaling, and drug delivery. In this chapter,we will review how the elastic properties of membranes control the membranes’ dynamics by presenting experimental results obtained by means of neutron spin echo spectroscopy. Toward the end of the chapter, we will consider another interesting property, membrane viscosity, and discuss some future aspects and challenges.
