In this study, the existence of localized surface plasmon resonance absorption associated with the nano-sized nature of Ag, Cu and Cu\/Ag particles was confirmed by the presence of a single peak around 487, 585, and 487\/580 nm respectively. Zeta potential and electrophoretic mobility were found to be 0.2 mV and 0.02 \u03bcmcm\/(Vs) for synthesized NPs indicating less stability and thus tendency to agglomerate, and broad distribution of particles. Cu-NPs and Cu\/Ag-NPs demonstrate that the dispersed phase is stable and has a minimum particle size at zeta potentials above \u201330 mV. Changes in phenolic compounds, total chlorophyll, and photochemical efficiency in leaves exposed to Ag, Cu and Cu\/Ag phyto-nanoparticles were evaluated up to 72 hours.
