A review on biogenic green synthesis of ZnO nanoparticles by plant biomass and their applications

Nanobiotechnology has recently gained prominence as a fundamental branch of modern science and a novel epoch in the field of material researches. Due to a wide range of applications it attracts attention of many scientists from all over the world. Bionanomaterials are prepared using a variety of physical, chemical, and biological techniques and methods. Many different metal and metal oxide nanoparticles are reported to be produced by biological systems, including bacteria, fungi, actinomycetes, yeasts, viruses, and plants. Among all of them, biocompatible zinc oxide nanoparticles (ZnO NPs), obtained through biosynthesis with the aid of plant-derived materials, appears to be a highly successful way to create a fast, clean, non-toxic, and environmentally friendly platform for the production and application of these bionanomaterials. This review focuses on the plant extract-derived ZnO NPs synthesis, with a special emphasis on the recent advances and applications of these nanomaterials.
