 Figure 2: Results of the control DNA (left) and touch DNA (right) persistence across varying environmental conditions on cotton and stainless steel over seven days

Description
              *This image is Figure 2 from the article Persistence of Touch DNA for Analysis.*

Figure 2: Results of the control DNA (left) and touch DNA (right) persistence across varying environmental conditions on cotton and stainless steel over seven days. The environmental conditions examined low temperature – low humidity (LT-LH), low temperature – high humidity (LT-HH), high temperature – low humidity (HT-LH), high temperature – high humidity (HT-HH), and under UV light. Note the increased range of variation in the touch DNA data.
