带电磷脂膜泡的内、外表面电荷密度和表面电位

本文按Gouy-Chapman理论,推导了稳定条件下磷脂膜泡膜内、外表面电荷密度/表面电位关系和表面电位分布以及带电磷脂在膜泡内外两侧的不对称分布的近似表达式.并对这些表示式的极限情况和可能的应用进行了讨论,同时对带电磷脂在膜泡膜内、外两侧的不对称分布也作了讨论.

THE SURFACE CHARGE DENSITY AND SURFACE POTENTIAL FOR A CHARGED PHOSPHOLIPID VESICLE

In this paper, according to the Gouy-Chapman theory, approximate expressions of the inner and outer surface charge density/surface potential relationship, and surface potential distribution as well as the asymmetric distribution of charged phospholipid molecules on the inner and outer layers for a phospholipid vesicle are derived at the steady state of phospholipid vesicle. The limit cases and posible applications for these expressions are discussed, the asymmetric distribution of charged lipid molecules on the inner and outer layers of a phospholipid vesicle is discussed also.
