Biofabrication of zinc oxide nanoparticles by using Lawsonia inermis L. seed extract

Biosynthesis of metal oxide nanoparticles via the green approach is an effective and eco-friendly method. The proposed investigation is focused on Zinc oxide nanoparticles (ZnO-NPs) synthesis from methanolic extract of Lawsonia inermis L. seeds. The seed extract contains phytoactive compounds which act as a reductant and stabilizer for the biosynthesis of ZnO-NPs followed by calcination. ZnO-NPs are characterized by different analytical techniques which provide information regarding its surface morphology, the average crystallite size (19 nm), estimation of the functional group involved in nanoparticles (NPs) synthesis. Gas chromatography-mass spectroscopy is helpful in the investigation of variant phytoactive compounds in the methanolic plant extract. UV-visible absorption spectra at 400 nm substantiate the formation of ZnO-NPs. ZnO-NPs is applicable in a wide range which includes fabrication of biosensor, optoelectronics, bio-medicals, etc.
