Biosynthesis of La2O3 Nanoparticles using Lawsonia inermis Leaf Extract

Abstract

The article explains the biogenesis of lanthanum oxide nanoparticles (La2O3 NPs) utilizing Lawsonia inermis extract as an easy, safe, and efficient approach. The La2O3 NPs were synthesized by reducing La(NO3)3.6H2O with Lawsonia inermis leaf extract as a reducing agent. Fourier-transform infrared spectra were used to determine how the biomolecules in the Lawsonia inermis leaf extract contributed to the synthesis of La2O3 NPs. The UV–visible spectrum of the biosynthesized La2O3 NPs revealed absorption peaks at the La2O3 NPs' absorption maxima, which is 245 nm. As per the scanning electron microscopy investigation, the biosynthesized La2O3 nanoparticles (NPs) with a size of 30 to 60 nm had an uneven shape. EDAX confirmed that La and O were present in the La2O3 NPs. La2O3 NPs were tested for their antibacterial properties Klebsiellapneumoniae and Multi Drug Resistant Staphylococcus Aureus. The antibacterial activity of the biosynthesized La2O3 NPs is mild.
