Green synthesis of silver nanoparticles using Croton sparsiflorus morong leaf extract and their antibacterial and antifungal activities

• Croton sparsiflorus morong acting as both the reducing and stabilizing agents.
• UV–Vis study shows the 457 nm as Ag NPs.
• XRD study confirmed the 26 nm as a particle size.
• FE-SEM confirmed the 22–52 nm as particles sizes with spherical in shape.
• FT-IR study shows the 1641 cm−1 as Ag NPs.

Biologically synthesized nanoparticles have been widely used in the field of medicine. Especially, silver nanoparticles (Ag NPs) synthesized by the leaf extract lead the biological activity. In the present work, the synthesized Ag NPs by using the leaf extract of Croton sparsiflorus morong Ag NPs were characterized by using UV–Visible (UV–Vis) absorption spectroscopy, X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FE-SEM) along with Energy Dispersive X-ray (EDX) Spectroscopy and Fourier Infrared (FT-IR) Spectroscopy, respectively. UV–Vis peak at 457 nm confirmed the Ag NPs due to the absorption. Cubic structural analysis and 16 nm particle size of the Ag NPs were calculated by using XRD analysis. The surface morphology along with the presence of Ag NPs was identified by using FE-SEM and EDX, respectively. The FT-IR study revealed with the functional groups of the Ag NPs. Finally, the present research has been explored to exhibit the significant antimicrobial activities.
