Abstract

This paper focuses on studying the impact of laser irradiation ( = 532 nm, power 15 mW) on human blood plasma. The structural changes in plasma were controlled by the crystallographic method with the mean crystallogram segment size as a numerical evaluation. In addition, the structural changes were explored by processing the speckle patterns obtained during laser radiation passes through plasma. Exposure to laser radiation of  = 532 nm for 20 min resulted in the 30% reduced the crystallogram characteristic size with the dynamics of the structural changes coinciding with the dynamics discovered by speckle patterns processing. The crystallographic method revealed that laser induced structural changes in plasma remain for 24–36 h after exposure.
