A long-living misconception is that the mismatch is between the TL and free-space impedances, ZTL ≪ Z0 [16]. However, this is not the source of the poor performance. On the contrary, it is

However, the presence of DNA molecules with single-base mismatches prevented the aggregation of AuNPs and the solution remained stable. This approach yielded a detection limit of 5 nM.
