Biofabrication of silver nanoparticles using Andrographis paniculata

• Biofabrication of AgNps by plant extracts is a simple and rapid method.
• AgNps are eco-friendly, efficient and cost effective.
• The average size of AgNps obtained from leaf extracts were of size 53 ± 54 nm.
• Highly stable due to its high negative Zeta potential, −50.7 mV.
• Biofabricated AgNps have very good antifungal activity.

New and novel strategies are of recent interest in the development of silver nanoparticles. The plant extracts are eco-friendly, economical and cost effective for synthesis of nanoparticles. In this paper, we represent biofabrication of silver nanoparticles (AgNPs) using Andrographis paniculata and the synthesized AgNPs was monitored by ultra-violet visible spectroscopy (UV–Vis). The morphology and crystalline nature of AgNPs were determined from scanning electron microscopy (SEM) with Energy dispersive X-ray (EDX), X-ray diffraction patterns (XRD), Fourier transform-infrared spectroscopy (FT-IR). The size and the stability were detected by using Nanoparticle analyzer. The average size of the AgNPs was found to be 54 ± 2 nm and the Zeta potential was found to be −50.7 mV. The synthesized AgNPs have very good antifungal activity.
