Water-soluble polymers carrying a small fraction of hydrophobic groups
are able to insert these groups into the hydrophobic interior of lipi
d bilayers or membranes. Under certain conditions such polymers can in
terconnect different vesicles or biological cells. With increasing pol
ymer concentration this leads to the formation of a three-dimensional
network. In this paper we report about the preparation and a first cha
racterization of the structure and the mechanical properties of these
new vesicle-polymer and polymer-cell gels composed of alpha,omega-chol
esterol-modified poly(oxyethylene) and dimethyldioctadecylammonium chl
oride vesicles or living cells.
