Synthesis and characterization of silver nanoparticles and their ...
The synthesis of silver nanoparticles (AgNPs) was successfully achieved using silver nitrate (AgNO₃) and sodium citrate as the reducing and stabilizing agents. The process involved the addition of sodium citrate solution to a boiling AgNO₃ solution, leading to the reduction of Ag⁺ ions to Ag⁰ and the formation of silver nanoparticles.
