[Selectivity and localized nature of exposure in laser microirradiation of cells].

Some modern applications of laser microirradiation to studies of relationship between structure and function are reported. The main advantage of the method is the ability to act on various subcellular parts and organelles, both locally and selectively. However, the degrees of laser microirradiation locality and selectivity are not always sufficiently high. These properties of laser microirradiation are analysed in addition to factors of deteriorating and improving the methods. It is assumed that the most important influence in cellular response to microirradiation is exerted by laser on different cellular membrane systems, particularly on the surface membrane and mitochondria.
