One-Step Green Synthesis of Metallic Nanoparticles Using Sodium Alginate

Figure 1

UV-vis analysis for the synthesis of copper (a, b, c), silver (d, e, f), and gold (g, h, i) nanoparticles using sodium alginate with a reaction time on MW of 3 min (a, d, g), 2 min (b, e, h), and 1 min (c, f, i). Black line is related to a concentration of 10 mM, red for 0.2 mM, and blue for 0.004 mM.
