Plant-Mediated Green Synthesis of Ag NPs and Their Possible Applications: A Critical Review

Figure 1

Fourier transform infrared (FTIR) spectra of Ag NPs synthesized using AgNO₃ (1 mM, 40 mL) and Piper chaba extract (100 g/L, 2 mL) after the reaction for 1 h at 60°C and pH = 7, and Ag NPs synthesized without capping agent reduced by NaBH₄ [59] (open access and reprinted under CC BY 4.0).
