Effects of Luminol on Blood and Solutions
Luminol reagent is a relatively "grounded" type of chemiluminescent reagent, which can often be seen in criminal investigation TV dramas. Luminol, commonly used in murder scene investigations, is a prepared solution. When sprayed on blood stains that cannot be recognized by the naked eye, iron ions in the blood catalyze the decomposition of hydrogen peroxide into water and monooxygen, which can oxidize Luminol to make it glow.
The reaction between luminol and blood is simply a chemiluminescence reaction with iron ions in the blood in the presence of hydrogen oxide, resulting in blue fluorescence. Using this characteristic, Luminol is also suitable for detecting the level of iron ions in the blood, but it has a certain destructive effect on the blood.
When luminol undergoes a chemiluminescence reaction with iron ions in the blood, oxidative stress occurs, which can lead to the destruction of blood components such as red blood cells, white blood cells, and platelets. This stress also reduces the ability of red blood cells to transport oxygen, impairs the hemostatic function of platelets, and affects the quality of blood samples.
The above effects are not significant in forensic testing of blood stains, as Luminol reagents do not damage DNA in the blood. However, some projects that destroy the original characteristics of blood samples after using luminol are not conducive to subsequent research, so substitutes with equivalent effects can be widely used; Alternatively, when using Luminol reagent, use protective agents such as antioxidants together to reduce damage to blood samples.
The use of Luminol has brought many conveniences to medical testing, as well as some challenges that need to be overcome. I believe that with the progress of technology, this problem can be easily solved in the near future. Hubei Xindesheng Material Technology Co., Ltd. specializes in the production of chemiluminescent reagents, including Luminol series products and acridine ester products.
