For this semester, I will be focusing my research on how fluorescent nanomaterials improve fingerprinting techniques. Some nanomaterials consist of quantum dots (QDs), nanoparticles (NPs), grapheme quantum dots (GQDs), and silicon nanoparticles (SiNPs). Traditional fingerprinting methods include powder dusting, cyanoacrylate fuming, chemical method, and small particle reagent method. These methods can have drawbacks such as low contrast, sensitivity, selectivity, and high toxicity. Introducing fluorescent nanomaterials can help achieve high contrast, sensitivity, selectivity, and reduced toxicity due to their unique optical and chemical properties. Over the course of the semester, we will research each method and find out why this has improved the overall technique of fingerprinting in forensic science.
