The UV-Vis absorption spectra of the cochineal solutions were obtained at pH 3.8 and 12.0 (Figure 1(a)).
EDS (Figure 4(c)) analysis confirmed that the particles were composed of silver when synthesized from cochineal solutions. The weight percentage of Ag in each sample (0.1ml and 0.4 ml of the cochineal extract) was similar because the volume of silver nitrate in the reagent was the same (Table 2).
