Dynamics of temperature dependent modifications of blood in the near-infrared.

Background And Objectives: Laser irradiation induces blood coagulation by heating of blood components. It is a complex phenomenon which encompasses a variety of processes, such as cell shape modification, cell membrane rupture, protein denaturation, aggregation, and finally blood gelation. An in vitro study was performed to investigate heating temperatures leading to transformation of blood and to have a better understanding of the dynamics of temperature dependent modifications of blood in the near-infrared.
