Figure 2: Structure and optical properties of ETE assemblies of Au NRs.
From: Attomolar DNA detection with chiral nanorod assemblies
(a–f) Representative TEM images for ETE assembly obtained after different number of PCR cycles, n=0 (a), 2 (b), 5 (c), 10 (d),15 (e) and 20 (f); scale bar, 50 nm. (g,h) Ultraviolet–visible (g) and CD spectra (h) for ETE assembly obtained for different n. (i) Intensity of absorption maxima for ETE assemblies obtained for different n. The error bars represent the standard deviation of sample measurements.
