Abstract
We consider the effect of tethered macromolecules on the stability of the flat conformation of a lipid bilayer in a dense brush regime when anchored chains are significantly overlapped. On the basis of a scalin g approach we have shown that redistribution of polymer chains from in ner to outer layers reduces the free energy of the system and stabiliz es spherically bent configurations of the membrane.
