INVESTIGATION OF CHARACTERIZATION, MAGNETIC AND ANTI BACTERIAL PROPERTIES OF NICKEL DOPED WITH MANGANESE/COPPER NANOPARTICLES PREPARED BY SOL-GEL METHOD

Abstract

The aim to study the effect of Nickel on structural, morphological, magnetic, antibacterial and antioxidant properties of sol gel derived manganese copper nanoparticles by sol gel technique with systematic investigation have been carried out. Manganese acetate dehydrate, copper acetate and nickel acetate tetra hydrate are used as the precursor material and dopant, respectively. The XRD pattern contained sharp peaks of Ni-manganese copper nanoparticles with mixed cuprite and tenorite phases. The morphologies of manganese copper nanoparticles were influenced by doping with Ni, as shown from the SEM images. The hysteresis loops of those Ni doped nanoparticles analogues displayed extremely magnetic scenery of those nanoparticles at room temperature which once saturation magnetization, coercivity and remanence magnetization reduced lineally over the increase in Ni-concentration in manganese copper nanoparticles. Pathogenic bacteria, such as Escherichia coli, S. Haemolyticus, Aeromonas hydrophila, Cronobacter sakazakii, Aeromonas salmonicida and Basillus subti were used to assess the antibacterial activity of the synthesized materials. The reduction in the viability of all the bacteria to zero using Ni-doped manganese copper nanoparticles occurred and it plays a vital role in the increased antibacterial activity performance. Here we concluded that the M4 is promising candidate for medicinal application because of higher magnetic properties, antibacterial and antioxidant activity compared to other samples.
