Abstract
In this study, we look into the biogenic synthesis of (AgNPs) utilizing a simple and environmentally friendly method based on an aqueous extract of Moringa Oleifera (MO). The synthesized MOAgNPs were characterized using a UV-Visible spectrophotometry, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectra and TEM image which confirmed the spherical shape of MOAgNPs with particle size range of 5-50 nm with an average particle size of 38.7 nm. Significantly, the prepared MOAgNPs showed high pesticidal activity towards Spodoptera littoralis. MOAgNPs also exhibited strong antibacterial activities against Gram-positive and Gram-negative bacteria. The prepared MOAgNPs were screened for their cytotoxic effect against (HCT-116), (HepG-2) and (MCF-7) carcinoma cell lines. Finally, the synthesized MOAgNPs have been used as a catalyst for the reduction of 2,4-Dinitrophenol using NaBH4 to 2,4-Diaminophenol. Taken together, the outstanding catalytic and biological activities of the synthesized MOAgNPs entitled them for applications as catalyst, pesticidal, antibacterial and anticancer agents in medical applications.
