Abstract

Caffeine is the most prominent stimulant for most people in everyday life. As such a prominent chemical in society, caffeine may be found at crime scenes and could factor into a criminal investigation. Previous research has focused on the effects of caffeine in the body, but never caffeine's direct effects on extracted DNA. In this project, four samples covering two different levels of caffeine concentration (control and DNA - caffeine sample) were tested to see caffeine’s direct effect on extracted DNA, more specifically if it has a preservation effect or not. DNA samples were collected and extracted from 4 different people (2 males and 2 females) and used in this study. To test the hypothesis, varying amounts of caffeine were added to the extracted DNA samples (saliva). Ultraviolet-visible spectroscopy and fluorescence were then conducted over the span for 4 weeks. The samples were then analyzed by comparing results of a calf thymus calibration curve over the time span. A preservation effect is expected to be found on the DNA over the time span. The results of this experiment could be implemented into DNA preservation strategies for crime scene investigations and will be shared.
