Additional file 1. Figure S1 Corresponds to Rumex hymenosepalus aqueous solution absorption spectrum. Figure S2 A band gap Tauc plot of AgNps, AuNps, and Au@AgNPs. Figure S3 XPS high-resolution for AgNPs, AuNPs, and Au@AgNPs. Figure S4 STEM images gallery of individual Au@AgNPs. The first column corresponds to Bright Field images and the middle column to HAADF. The last column is shown manipulated images using ImageJ to enhance contrast. We can observe the uniformity of the Ag-shell. Figure S5 AuNPs HRTEM (A), region 1 FFT plot (B), and integrated image from FFT (C). Region 2 FFT plot is shown in (D) and integrated image from FFT with interplanar distances in (E). Figure S6 AgNPs HRTEM (A), FFT plot (B) and, integrated image from FFT with interplanar distances (C). Figure S7 Variations of atomic content percentage versus increase thickness shell. Figure S8 C. albicans dose-response curve comparative between Ag and Au@AgNPs. Table S1-S54. Adjust parameters of the curve by modified Gompertz Model (Origin 2018 software) and Physical Parameters of Bacterial Growth obtained with Adjust Parameters for S. aureus, E. coli, and C. albicans at concentrations 0, 1, 10, 50, and 100 µg/mL, respectively. Figure S9 Minimal Bactericidal Concentration determined for E. coli treated with nanoparticles and inoculated in Muller Hinton plate. AgNPs (A), AuNPs (B), and Au@AgNPs (C). Figure S10 Minimal Bactericidal Concentration determined for S. aureus treated with nanoparticles and inoculated in Muller Hinton plate. AgNPs (A), AuNPs (B), and Au@AgNPs (C). Figure S11. Minimal Bactericidal Concentration determined for C. albicans treated with nanoparticles and inoculated in Muller Hinton plate. AgNPs (A), AuNPs (B), and Au@AgNPs (C) Table S55.
