Unlocking Secrets: DNA Clues from Explosive Devices

Explosive devices made from everyday items are often used by criminals. Even after these devices go off, tiny bits of DNA can sometimes be found. This DNA can come from skin, blood, or other body fluids. But, it's often in bad shape and hard to study. Scientists did a study to see how well they could find and study this DNA. They put DNA from different sources on different parts of the devices. Then, they blew them up using different amounts of dynamite. After the explosion, they tried to collect and study the DNA.They found that many things affect how well they can study the DNA. These include the type of DNA, the amount of dynamite used, the part of the device, and the material it's made of. They also found that DNA from blood was the easiest to study, even after big explosions. DNA from skin contact was also found, especially on batteries. This study shows that it's possible to find useful DNA clues from explosive devices. But, it's not easy. The results can vary a lot based on many different factors. This information can help forensic investigators in their work.
