Abstract

The addition of modified (stealth, grafted) lipids to a phosphatidylcholine bilayer changes the elastic properties of the membrane. The dependence of the bending and stretching elasticities of the bilayer on the concentration of the modified lipid and on the number of units in its polymer chain are calculated. Using the micropipette technique, the bending elasticity of the membrane for several concentrations of the modified lipid is measured. Comparisons are made between the theoretical predictions and the experimental data.
