ABSTRACT
The green synthesis of silver nanoparticles (AgNPs) and the applications have used many fields as the AgNPs are used effectively in microorganisms. The purpose of this study is to synthesize and characterize silver nanoparticles used the plant leaves of Andrographis paniculata as well as to test their effectiveness in antimicrobial activity. In this study, at 0.1 mM concentration of silver nitrate (AgNO3), stable AgNPs were synthesized and monitoring the colour change of the solution. The crystalline nature of these AgNPs was detected through an (XRD) pattern and confirmed the functional compunds as well the AgNPs were characterized through ZETA Potential to the study the morphology and size of the nanoparticles (NPs). And checked their effective of cytotoxicity test.
