Conformational Transitions of Mixed Monolayers of Phospholipids and Poly(ethylene oxide) Lipopolymers and Interaction Forces with Solid Surfaces Thomas R. Baekmark, Gunther Elender, Daniel D. Lasic, and Erich Sackmann* Langmuir 1995, 11, 39753987. In Figures 2b and 3c an error in the calculation of the lateral compressibility, κ, has occurred. Corrected versions of the two figure are presented. The correction of the graphs leads to the following change: On page 3978 line 9 we note, based on the erroneous graphs, that the phase transition of DSPE-EOn at πtlow cannot be characterized even as a second-order phase transition. This statement no longer holds true since κ exhibits a peak also for πtlow which, according to the Ehrenfest definition of phase transitions, is characteristic of a first-order phase transition. All other conclusions presented in section III.1 and in the discussion thereof remain unchanged. On page 3975 line 40 we state that the Flory radius of the lipo-polymer DSPE-EO110 is 75 Å. This is incorrect. Instead a value of 60 Å should be used. All values derived from the incorrect Flory radius are changed accordingly, but again the conclusions remain unchanged.
