Cobalt, Copper and Magnesium Doped Nickel Zinc Nanoferrites by Solution-Combustion Method: Structural, Antibacterial and Antifungal Properties

The nickel zinc nanoferrites with configurationNi 0.45 Zn 0.55–x M x Fe 2 O 4 were achieved where x = 0.0, 0.1, 0.2 and 0.3 and M = Cobalt, Copper, Magnesiumusing solution-combustion method by availing sucrose as a fuel. The procured nanoferrites were investigated forstructural properties using TEM, antibacterial and antifungal propertiesby Kirby-Bauer Disk Diffusion Susceptibility Test also calledas Agar diffusion method. The synthesized nanoferrites were tested for their antibacterial activities against Gram negative ( Escherichiacoli ) and Gram positive ( Bacillus cerus ) bacterial strains. Also, investigation was evaluated for their antifungal activity against Aspergillus niger . Against Bacillus cerus, sample Ni 0.45 Zn 0.45 Cu 0.1 Fe 2 O 4 showed maximum antibacterial activity. The maximum antifungal activity was observed for Ni 0.45 Zn 0.35 Co 0.2 Fe 2 O 4 .
