Aluminium substituted ferrite nanoparticles with enhanced antibacterial activity

In this article, the synthesis of Aluminium doped copper-cobalt ferrite nanoparticles with enhanced antibacterial activity and magnetic properties are reported. The Co_1-xCu_xFe_2-xAl_xO₄ (00 = x = 08) particles are prepared by varying doping concentration using co-precipitation technique. The structural characterizations confirm the formation of spinel structure. The substitution of aluminium in copper-cobalt ferrite nanoparticles strongly influence the crystal structure, and particle diameter, and also improves the antibacterial characteristics. The anti-bacterial activity is tested on Gram negative (Escherichia coli or E. coli) and a significant enhancement in antibacterial activity is observed with increase in Aluminium doping ratio.
