Nanoscale characterization of forensically relevant epithelial cells and surface associated extracellular DNA

Epithelial cells of various types line the exterior skin and interior cavities of human bodies. In the case of skin, the outermost layer is composed of keratinized, stratified squamous epithelial cells. In contrast, tissues that line the inside of the mouth, or the esophagus are composed of non-keratinized, stratified squamous epithelial cells.[1] Both kinds of epithelial cells are important in various forensic contexts owing to cellular and DNA transfer onto surfaces through contact with skin and saliva, respectively.
