Metallic Nanoparticles Synthesized Through Medicinal Plants: Therapeutic Improvement

<div>The field of nanotechnology has developed new medicinal nanoparticles that</div><div>have various uses in pharmaceutics and healthcare. Distinct macroscopic and</div><div>microscopic entities including plants, fungi, microalgae, bacilli, and seaweed have been</div><div>used to biosynthesize nanoparticles. Naturally-occurring chemicals like flavonoids,</div><div>tannins, alkaloids, steroids, and saponins are abundantly present in plants. A potentially</div><div>unharmful method to produce nanoparticles can be through extracts of different plants.</div><div>As plant extracts carry many specialized metabolites, they can act as stabilizers and</div><div>reducers in bioreduction reactions that take place in metallic nanoparticle production.</div><div>The production of metallic nanoparticles by biological techniques is an easier, cheaper,</div><div>and more environmentally sound option in comparison with other physical and</div><div>chemical techniques that are extremely toxic and unsafe for biological use. Greener</div><div>nanoparticles like Co, Cu, Ag, Pd, Au, ZnO, Pt, and Fe3O4 have been biosynthesized</div><div>using medicinal plants. These nanoparticles have various uses in pharmaceutics ranging</div><div>from gene delivery, drug delivery, pathogen detection, tissue engineering, and protein</div><div>detection. Not only that but, metallic nanoparticles can also potentially be remedies to</div><div>different acute diseases including hepatitis, human immunodeficiency virus, malaria,</div><div>and even cancer. Improvements in drug delivery and tissue engineering have been</div><div>made possible by nanotechnology and this has greatly facilitated translational level</div><div>studies that relate to pharmaceutics. In this chapter, green syntheses of metallic</div><div>nanoparticles through medicinal plants along with their uses in therapeutic</div><div>improvements are described.</div>
