This review discusses photomodification of biological membranes and model membrane systems. Current concepts of membrane structure are first reviewed briefly. The role of preillumination association of sensitizer with membranes as it relates to photomodification rate is discussed, as well as the role of singlet oxygen in membrane photomodification. Finally the characteristics of singlet oxygen generation in membranes are considered. The evidence clearly indicates that membrane photomodification cannot be understood based only on the properties of sensitizers and singlet oxygen in aqueous solution. Rather the properties of sensitizers in association with membranes are the determinants of membrane photomodifcation. These properties differ significantly in aqueous solution and in membranes.
本综述讨论了生物膜和模型膜系统的光修饰。首先简要回顾了当前的膜结构概念。讨论了敏化剂与膜预光照结合在光修饰速率方面的作用，以及单线态氧在膜光修饰中的作用。最后考虑了膜中单线态氧生成的特性。证据清楚地表明，仅基于水溶液中敏化剂和单线态氧的性质无法理解膜的光修饰。相反，与膜结合的敏化剂的性质才是膜光修饰的决定因素。这些性质在水溶液和膜中存在显著差异。
