Abstract |
|
The present work reports on simple and effective ecofriendly approach for the synthesis of silver nanoparticles (AgNPs) from Spaghetti squash which act as a reducing and capping agent. The synthesized silver nanoparticles were confirmed by color transformation and Ultraviolet-visible (UV-visible) spectrophotometery. Surface Plasmon Resonance (SPR) for AgNPs was observed at 422 nm. The size and morphology of the silver nanoparticles were characterized by Scanning Electron Microscope (SEM). The synthesized AgNPs were found to be spherical shape with average diameter of 46 to 41 nm. The silver nanoparticles synthesized were evaluated for their antibacterial efficacy against all the tested microbial strains and insecticidal activity was conducted at varying concentrations for 24 hrs at 500 mg/ml was the highest insect mortality effect. |
