Fig. 8From: Green nanopriming: responses of alfalfa (Medicago sativa L.) seedlings to alfalfa extracts capped and light-induced silver nanoparticlesThe process of light-induced synthesis of AgNPs and the reduction of its toxicity. A Natural light irradiation makes AgNPs aggregated; B In the solution, Ag+ from AgNO3 undergoes a reduction reaction; C The remaining substances wrapped the AgNPs through electrostatic interaction; D The light-induced AgNPs releases less than 2 % Ag+Back to article page
