Grouping percentage of nAu–DNA conjugates with different ratios of target DNA. Lanes P–T correspond to nAu–A and nAu–revA with target DNA at a ratio of 2:1:2 (nAu–A:nAu–2x revA:target DNA), 2:1:5, control (nAu without Strand A/revA conjugation), 2:1:20 and 2:1:100, respectively. Gel picture shows the combined results from two experiments.
