Abstract

Quickly developing industrialization is one of the significant benefactors of natural contamination as it presents awful difficulties for the earth and the ordinary citizens. Biological synthesis of the silver nanoparticles (AgNPs) atthe presence of the aqueous leaf extract of Celosia argentea, funtioned as the reducing and capping agent. In this research study, we are reportthe synthesis of the AgNPs with the optimized experimental parameters at the pH. Formation of the AgNPs was confirmed by the UV-Visible spectroscopy and FT-IR analysis. The structural characterization was carried using the SEM-EDX, providing the size of the nanoparticles to be 50-80 nm. The AFM showed the spherical surface topology, the zeta potential whereas, particle size analysis showed stability and the average size was determined to be 50 nm.

“…It has many advantages, including environmental friendliness and suitability for pharmaceutical and biomedical applications [6,7]. For the synthesis of silver nanoparticles, the literature reports different plants such as Eichornia crassipes [8], the skin of Citrus sinensis [9], the extract of the roots of carissa carandas [10], leaves and barks of Ocimum basilicum [11], flowers of the parasitic plant Cascuta reflexa [12], plant residues of Artocarpus altilis [13], flowers of Spartium junceum [14], seeds of Xanthium strumarium [15], and leaves of celosia argentea [16]. In the present work, the plant of combretum micranthum was used for the green synthesis of silver nanoparticles because of its availability, antioxidant properties and its numerous virtues, especially for the treatment of some diseases such as diabetes, diarrhea, hepatitis, jaundice [17,18].…”
