Abstract

original image

The molecular recognition between cholera toxin B and GM1-functionalized phospholipid/block copolymer hybrid membranes can be controlled by varying the lipid/block copolymer composition. Confocal laser scanning microscopy and fluorescence correlation spectroscopy were used to study the protein–receptor interaction and dynamic processes in the membrane.
