Fig. 2From: Synthesis and analysis of silver–copper alloy nanoparticles of different ratios manifest anticancer activity in breast cancer cells EDS spectra of nanoparticles. The silver and Copper spectral peaks identified in EDS spectroscopy, as shown in figures, represent Ag-NP, Cu-NP, AgCu-NP 50:50, AgCu-NP 70:30, AgCu-NP 30:70Back to article page
