"MgO Nanostructures from *Piper betle*: Photocatalytic, Antioxidant, and Antibacterial Properties

What is it about?

This study explores the synthesis of biocompatible magnesium oxide (MgO) flake-like nanostructures using Piper betle leaf extract as a green reducing and stabilizing agent. The novel MgO nanostructures were characterized by various analytical techniques, including X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier-transform infrared spectroscopy (FTIR), confirming their unique morphology and crystallinity. The synthesized MgO nanostructures exhibited significant photocatalytic activity under visible light, efficiently degrading model pollutants such as organic dyes. Additionally, they demonstrated notable antioxidant properties, as evidenced by their free radical scavenging ability in DPPH and ABTS assays. Antibacterial tests against Gram-positive and Gram-negative bacteria revealed potent antimicrobial activity, highlighting the potential of these MgO nanostructures as effective antibacterial agents. The biocompatibility and multifunctionality of these nanostructures suggest promising applications in environmental remediation, biomedical fields, and as a sustainable alternative in nanomaterial synthesis.
