In forensic science, criminal investigation, and biomedical research, luminol has emerged as a fluorescent substance in blood testing. Blood can provide important clues about an individual's health status, genetic information, and behavioral patterns, but due to the fact that blood samples are often trace and easily contaminated, an efficient, sensitive, and reliable detection method is needed. Lumino blood testing is a blood testing technique based on chemiluminescence reactions, which has the advantages of high sensitivity, specificity, and speed. Therefore, it has been widely used in forensic science, criminal investigation, and biomedical research. The basic principle of Lumino blood testing Lumino is a compound with a special chemical structure that can undergo chemiluminescence reactions in the presence of peroxides. When hemoglobin in the blood reacts with luminol, iron ions in hemoglobin catalyze the decomposition of peroxides to generate energy, which in turn excites luminol to emit specific wavelengths of fluorescence. By measuring the intensity of the luminescence, the presence and concentration of blood can be determined. Lumino blood testing also has high specificity. Due to the fact that iron ions in hemoglobin can only react with specific chemicals when catalyzing the decomposition of peroxides, luminol blood testing can effectively avoid interference and improve the accuracy of detection. The application of Lumino blood testing 1. Forensic applications: In forensic science, the Lumino blood test is widely used for on-site investigations and court evidence collection. By detecting biomarkers such as DNA, proteins, and metabolites in the blood, information about criminal behavior, time of death, and cause of death can be obtained. 2. Criminal investigation application: In criminal investigation, Lumino test can help detectives find clues to suspect. By detecting trace amounts of blood left at the scene, information about the suspect's identity characteristics, behavior patterns, and other related cases can be obtained. 3. Biomedical research applications: In biomedical research, luminol blood testing is widely used in disease diagnosis, drug development, and efficacy evaluation. By detecting biomarkers in the blood, information about the occurrence, development, and treatment effects of diseases can be obtained. In addition, luminol blood testing can also be used for gene expression analysis and cell function research.
