The UV–visible spectra of the Au NPs added to the oligonucleotides subjected to different hybridization conditions in terms of flash heating: a, d no flash heating, b, e 95 °C for 30 s, and c, f 95 °C for 120 s. The top and bottom row experiments were performed with 1.5 and 3.0 μM concentrations of the oligonucleotides, respectively. The respective symbols T and C represent target and control, while the experiments performed with the addition of citrate buffer were coded with (cit). The final concentrations of the NaCl were also mentioned alongside the sample code
