Abstract
Trace DNA, widely known as Touch DNA, is a type of DNA evidence commonly found at crime scenes, and it is frequently used to link suspects to crimes committed but it is a more challenging type of DNA evidence compared to other biological samples. This study investigated the influence of collection method and extraction type on Touch DNA collected from fabric. The amount of collected Touch DNA from the fabric was significantly affected by collection type (p < 0.05), with Scene Safe Fast™ minitape (K545) being more efficient than Copan cotton swab (150C) and Copan nylon flocked swab (4N6FLOQSwabs®) on recovering touch DNA from fabric.
