Abstract :

The (Ag-Cu) bimetallic nanoparticles was synthesized from the leaf extract of Celtis integrifolia using the silver nitrate (AgNO3) copper chloride (CuCl2) as a metal precursors. The synthesized bimetallic nanoparticles was characterized using UV-visible spectrophotometry, the celtis extract shows highest peak at 300nm due to plasma vibration and excitation of bio reduction capping agent Ag-CuNPs shows peak at 300nm which is due to surface Plasmon vibration, indicating the formation of bimetallic nanoparticles due to the excitation of the surface Plasmon vibration and phytochemical constituent present in the extract. FT-IR identify the functional groups present, SEM shows the morphology of the bimetallic Ag-CuNPs is partially merely crystalline and spherical in nature. XRD analysis of Ag-CuNPs showed face centered cubic structure (FCC) with average particle size of 54.42. The (Ag-CuNPs) bimetallic nanoparticles shows significant antibacterial and anti-fungal activity when tested against Escherichia-coli, pseudomonas aureginosa (Gram-negative), staphylococcus aures, Klebsella Pneumonia (Gram-positive) bacteria’s and two fungi Aspagillus niger and Candida using Augomentine and Fulcin as control drugs.
