Maranta arundinacea root assisted zinc oxide nanoparticles and its characterisation using TEM and UV-vis spectroscopy

Abstract

Arrow root is a tropical root crop cultivated for its starchy rhizomes that have carbohydrate contents. Zinc oxide nanoparticles have emerged a promising potential in biomedicine, especially in the fields of anticancer, wound healing, free radical scavenging and antimicrobial including antibacterial, antifungal and antiviral research fields, which might be worried with their potent ability to trigger extra reactive oxygen species (ROS) production, launch zinc ions, and induce mobile apoptosis. 1 gram of Arrow root powder extract was mixed with 100 mL of water and filtered for nanoparticles synthesis. The zinc sulphate was used as a precursor for the zinc oxide nanoparticles synthesis and 30 mM was used. 50 mL of freshly prepared root extract and zinc sulphate solution was added together for the synthesis of Zinc oxide nanoparticles, which was then dried and characterised using transmission electron microscope (TEM) and during reaction it was characterized using UV-vis spectroscopy method. A spherical shaped nanoparticle with plant extract in the background was observed. The peak at 300 nm confirm the nanoparticles synthesis using root extract. Based on our results we confirmed the capability of arrow root for the zinc oxide nanoparticles synthesis and it will be used for the various biomedical application in future.
