Advances in the field of nanoscience and nanotechnology to modulate materials at nanoscale level has continued to have great impact on different disciplines of science and engineering as well as agriculture and medical fields. Metallic and metal-oxide nanostructures have shown great potential due to their high surface to volume ratio and high reactivity. Among them, LaO has revealed wider applicability, including in nanomedicine, where LaO nanomaterials have shown great potential leading to effective interactions with biological membranes and exhibiting antibacterial and/or anticancer behaviors. In the current study, the biosynthesis of La2O3 NPs was attained by a biosynthesized method by using the aqueous leaf extract of Eclipta prostrata. La2O3 NPs were characterized by UV, FTIR, XRD, SEM, FL, PSA and TGA methods. The X-ray diffraction displayed the existence of La2O3 NPs which is confirmed by the incidence of peaks at 28.32 corresponds to 002 anatase form. The La2O3 NPs showed significant antimicrobial activity against all the tested microorganisms.
