(a) The reproducibility of HAuNFs substrates measured with NBA (1 × 10−8 M). (b) SERS stability of NBA-labeled HAuNFs substrates measured with NBA (1 × 10−8 M). HAuNFs substrates were stored for several days at room temperature. Inset image was SERS intensities of the bands at 592 cm−1 corresponding to the SERS spectra (b). (c) SERS spectra of HAuNFs substrates measured with NBA from 1 × 10−8 M to 1 × 10−12 M. (d) SERS spectra of (black curve) HAuNFs substrates treated with 0.1 M KI and (red curve) HAuNFs substrates without being treated with 0.1 M KI.
