The present investigation was aimed to study the biosynthesis, stability and characterization of silver nanoparticles using Achyranthes aspera root extract. Synthesis of silver nanoparticles has been done by maintaining different AgNO3 concentrations (, , and mM), temperature (25, 45, 75, 105 and 125 ºC) and pH conditions (4, 5, 7, 9 and 10). By analysing the data obtained during stability study, it was found that, combination of AgNO3 of mM concentration, temperature at 45 ºC and pH of 9 was the best condition to synthesize the stable Ag NPs for one month. | Stability of biosynthesised silver nanoparticles using Achyranthes aspera roots and its characterization
