| Abstract: | Objective To develop a highly sensitive luminescent reagent for bloodstain testing at forensic crime scenes.Methods Based ontheprincipleof ECL luminescence and the ping-pong conjugate activation principle of chemical electronic chain,this project developed a new type of highly sensitive luminescent reagent for bloodstain testing by usingthe uniform design of experimental methods to optimize the conditions andsynthesize several new compounds.Results The bloodstain testing luminescent reagentdeveloped in this project has high sensitivity andlongluminescence time.In the case of blood samples diluted by 1,000 times,reading the fluorescence withChemiScope 3300 chemiluminescence imaging system,the maximumvalue of gray scale reached 56,and the luminescence time lasted for 10 minutes.Conclusion The project has successfully developed a highly semitivebloodstain testing reagentthat could be applied to crime scene investigation. |
