(a) Cyclic voltammetry showing the rapid reduction of silver ions using silver electrode as reference and scan rate of 1000 mV S⁻¹ (arrow is showing the event of addition of plant extract in the reaction mixture) and (b) open circuit potential during the synthesis of SNPs, points A-B represent the potential of KNO₃ after addition of AgNO₃ solution, C is the point where the plant extract was added, and D-E show wide constant potential of SNPs after reduction of Ag⁺ ions to Ag⁰.
