Plant-Mediated Green Synthesis of Nanoparticles

Abstract

Nanoparticles are an inspiring group of nanostructured materials with broad-spectrum applications in different fields such as catalysis, antimicrobial treatment, drug delivery, nanomedicine, environmental remediation, electronics, and chemical sensors. Nevertheless, the techniques used for preparation are environmentally unfriendly. Aiming to promote the greener synthesis of nanoparticles, this chapter spotlights plant-mediated eco-friendly and sustainable development of nanoparticles. Naturally occurring plant extracts are enriched with a plethora of various biologically active biomolecules and secondary metabolites, including alkaloids, terpenoids, flavonoids, enzymes, and phenolic substances. These bioactive compounds can catalyze the reduction of metal ions into biogenic nanoparticles in an eco-sustainable single-step biosynthetic process. Additionally, the utilization of plant extracts and their derived compounds circumvents the necessity for capping and stabilizing agents and generates bioactive size and shape-dependent green nanoparticles. Herein, we have made an effort the describe the synthesis of a wide range of metal-based nanoparticles (platinum, gold, zinc oxide, silver, and titanium dioxide nanoparticles) by using plant extract as a green synthesis matrix. In addition, different parts of plants that have widely been utilized for the biosynthesis of these NPs with several sizes and shapes by biological 2 methodologies are briefly described. In conclusion, the greener synthesis approaches are safer and easier to exploit the massive preparation of nanostructured particles.

Therapeutic Effects of Natural Products on Cervical Cancer: Based on Inflammatory Pathways

“…Biosynthesis of metal nanoparticles is a simple, safe and green way of synthesis. In biosynthesis, various parts of plants and fungi can synthesize metal nanoparticles (Ahmed et al, 2016a;Ahmed et al, 2016b) and adjust the size and shape of nanoparticles because biologically active compounds in plants can accelerate the conversion of metal ions into biologically active nanoparticles (Munir et al, 2021). The researchers took note of biosynthesis and investigated the effects of plant-based metal nanoparticles.…”

Medicinal plants mediated the green synthesis of silver nanoparticles and their biomedical applications

“…These medicinal herbs are high in alkaloids, phenolics, and tannins. Such biologically active compounds in plants could indeed speed up the conversion of metal ions into biologically active nanoparticles in an environmentally friendly standard biosynthesis pathway [7]. Plant components such as fruits, leaves, stems, seeds, flowers, roots, bark, rhizome, and fruit peel are used in the production of various types of nanoparticles [8].…”

“…AgNPs green synthesis had already been shown to be a promising and environmentally friendly method [17]. The green synthesis method makes the mass production of nanoparticles safer and less expensive [7]. In this review, we discussed the formation of medically valuable AgNPs and their characterisation, various biomedical features of AgNPs with their mechanism of action and also the potential hazardous effects of AgNPs.…”

An Overview of Nanofiltration and Nanoadsorption Technologies to Emerging Pollutants Treatment

“…Chemical methods are widely used because they present high yield of nanoparticle production with low economic investment [119][120][121][122][123]. Another method used is the wet chemical reduction, which allows the morphological control of the developed nanomaterials and incorporates organic or inorganic ligand [124].…”
