Shelf-life enhancement of donor blood by He-Ne laser biostimulation

摘要

Shelf life of stored blood in a bank is an important parameter for the effective use of blood drawn from the donors. Several attempts have been made (such as antioxidant treatment and magnetic field intervention) to improve the above lifetime of 42 days. Here, we show that biostimulation by a He-Ne laser could enhance the shelf life to 63 days. The results are based on the fragility and conductivity measurement of red blood cells.
