Breakthrough in Nanotechnology: Magnesium Oxide Nanoparticles Derived from Banana Peels Exhibit Antimicrobial Properties

Researchers at the University of Basrah in Iraq have successfully synthesized Magnesium Oxide nanoparticles (MgO NPs) from banana peels, exhibiting antimicrobial properties suitable for packaging materials. The nanoparticles demonstrated sharp absorption peaks in the ultraviolet spectrum, spherical granular structures, and antibacterial and antioxidant activity, with non-toxicity to cells. This biodegradable and eco-friendly approach has the potential to revolutionize the packaging industry.

Key Takeaways:

  • The research involved the preparation of MgO NPs through aqueous extraction of banana peels, followed by characterization and incorporation into polymer matrices.
  • The resulting particles showed sharp absorption peaks at 350 and 500 cm^-1 in the ultraviolet spectrum.
  • SEM and TEM revealed MgO NPs as almost spherical granular structures.
  • XRD showed six main peaks of the crystalline mineral elements of the magnesium oxide nanoparticles.
  • FTIR results confirmed biologically active compounds act as reducing and capping agents for the nanoparticles.
  • The magnesium oxide nanoparticles demonstrated antibacterial and antioxidant activity and non-toxicity.
  • This research has been peer-reviewed and published in the Cellular and Molecular Biology journal.

Statistics:

  • The ultraviolet spectrum of MgO NPs showed sharp absorption peaks at 350 and 500 cm^-1.
  • SEM and TEM revealed MgO NPs as almost spherical granular structures with a diameter of approximately 50-100 nm.
  • XRD showed six main peaks of the crystalline mineral elements of MgO NPs.
  • FTIR results confirmed biologically active compounds as reducing and capping agents for MgO NPs.
  • The research demonstrated antibacterial and antioxidant activity with non-toxicity in cellular models.
