Objective: The present investigation determines the biological synthesis and characterization of Copper oxide nanoparticles from aqueous extract of Eichhornia crassipes and assessing its effects on antimicrobial activity against the pathogens.

Methods: In this method Eichhornia mediated copper oxide nanoparticles were synthesized and characterized by FT-IR, FESEM and EDX and also antimicrobial activity was determined using the well diffusion method.

Results: The antimicrobial activity of Eichhornia mediated copper oxide nanoparticles was tested against selective pathogens and maximum zone of inhibition was observed in S. aureus and A. flavus at 100 µg/ml concentration.

Conclusion: The green synthesized copper oxide nanoparticles have antimicrobial activity against selective microorganisms and it can be effectively used as a good antimicrobial agent.


Keywords: Copper oxide, Eichhornia, EDX (Energy-dispersive X-ray spectroscopy), FESEM (Field emission scanning electron microscope), Fourier transform infrared spectroscopy (FT-IR), Nanoparticles and Antimicrobial activity
