Lipids are the main constituent of biological cell membranes. Whetherthere are lateral heterogeneities in lipid composition, called 'rafts', in cell membranes is a matter of great debate and controversy among biologists. I look at a binary lipid system (DPPC & DPPE) where the lipids have different hydrophilic head groups but the same hydrophobic tails. These lipids are used to form giant unilamellar vesicles of similar size to biological cells that can be imaged using optical techniques. I will discuss the domain formation and domain morphology observed for this system on cooling from a fluid state to a gel phase.
This is a weekly series of informal talks given primarily by members of the soft condensed matter and statistical mechanics groups, but is also open to members of other groups and external visitors. The aim of the series is to promote discussion and learning of various topics at a level suitable to the broad background of the group. Everyone is welcome to attend..
