Agarose gel electrophoresis image of pBR322 plasmid DNA ([DNA]_bp = 15 µM) incubated with 2, applying different pre-irradiation and incubation times and using two complex concentrations, namely 12.5 µM and 50 µM. Lane 1: DNA, lane 2: DNA with pre-irradiated buffer (DNA)*, lanes 3–9: [complex] = 12.5 µM, lanes 10–16: [complex] = 50 µM. Lanes 3 and 10, dark control. For lanes 4–9 and 11–16, the preirradiation and incubation times are mentioned above each lane in minutes, as preirradiation time + incubation time
