Biological synthesis of nanoparticles using Aloe vera, Chamomile, and Licorice extracts

Nanotechnology is now an integrated feature of most modern research in agriculture. Nanomaterials are being widely used for enhancing soil fertility and strengthening its organic cycle and subsequently, improving yields of important crops. These particles can be prepared easily through different chemical, physical, and biological approaches. In this paper, biological method of preparation of Zinc, Iron, and Silver nanoparticles are described using the extracts of three medicinal plants which are commonly used for their important pharmaceutical properties, namely chamomile, licorice, and aloe vera. Also, the analytical techniques used to confirm the quality of the produced bio-NPs are explained.
