| The purpose of this research is to investigate the different factors that can contribute to the luminol reaction in the detection of bloodstains. Luminol is a blood-detecting reagent that chemiluminesces blue whenever it comes in contact with blood and is commonly used by both forensic scientists and blood pattern analysts. Different environmental factors, primarily temperature and precipitation, were examined for their effect on the ability of luminol to detect bloodstains on different surfaces. Different parameters related to the luminol reaction, including the base used in preparation, the use of organic solvents, the substrates to which the blood is applied, and the dilutions of the blood were also varied. The intensity of the chemiluminescence of each solution was measured using the fluorimeter, and a check whether those results correlated to the chemiluminesence on different substrates was performed. This research attempts to solve the problem of the distortion of blood patterns on smooth surfaces sprayed with luminol. |
