Green Synthesis of Ag NPs Using Ustilago maydis as Reducing and Stabilizing Agent

Figure 5

SEM of Ag NPs obtained under 0.1 g or 0.9 g of U. maydis at pH 9 and pH 11 after 100 seconds of sunlight exposure at room temperature with inserts that demonstrate the formation of Ag NPs, the agglomerations, and the encapsulation of Ag NPs with structures that contain C element related with UM presence.
