Abstract: 
Investigations on some bioactive Fe and Co Nano Particles as bimetallic Fe-Co nanoparticles were synthesized using Mentha piperita leaf extract as reducing agent. Hydrated Co and Ni reagents were utilized as metals precursors. The study was aimed to synthesized Nano Particles and characterized them using UV-Visible spectrum which showed Fe-Co Nps highest absorbance at a peak of 400nm. FTIR of leaf extract revealed that 3432cm-1 (O-H), 2936 cm-1(C-H) stretching, 1638 cm-1(N-H) 1340 cm-1 (N-O) and 659.38 cm-1 (C-C) functional groups, while Fe-Co Nps showed the same with addition of 1694 cm-1 (C=O) and 666.04 cm-1 (C-C) triple bond.  XRD analysis showed peaks to the plane (111), (110), (211) and (220) representing face centered cubic (FCC) structure whose size of 52.64nm. SEM analysis showed irregular cubic and hexagonal shape of different sizes. Antibacterial activity of Fe-Co Nps showed increase in bacterial growth in Eschemicha-coli while psendomonas aureginos (Gram-negative) and Klebsella pneumonia (Gram-positive), showed inhibition with increase in concentration of the synthesis drug. Antifungal activity test on Fe- Co NPs revealed that Aspagillus niger shows an increase growth inhibition with increase in concentrations of synthesis drugs the process of activity was the same in case of Candida fungi
