摘要：

This paper describes the morphological characterization of aqueous dispersions of PC amphiphiles and bolaamphiphile AEC by microscopy, the liposomal membrane fluidity, and the zeta potential. Results indicate that the bolaamphiphile AEC can be included within conventional egg-PC liposome bilayers. This behavior could be due to their preference for the stretched conformation within the PC membranes. (C) 2003 Elsevier Inc. All rights reserved.
