A novel approach to the green synthesis of metallic nanoparticles: the use of agro-wastes, enzymes, and pigments

Abstract

The green synthesis of nanoparticles has received great attention in recent times owing to its advantages such as cost effectiveness, simplicity, eco-friendliness, biocompatibility, and wide applications over the conventional chemical and physical methods. Various kinds of biomolecules from microorganisms and plants have been successfully utilized for the synthesis of metallic and nonmetallic nanoparticles, and these have been well documented. However, the recent increase in the fabrication of metallic nanoparticles using agro-wastes, enzymes and microbial and plant-derived pigments and their respective areas of applications have not been compiled as a review article. Therefore, the present efforts have been aimed at compilation of reports on the use of these novel bio-resources for the green synthesis of nanoparticles. To the best of our knowledge, this is the first review article on the green synthesis of metallic nanoparticles using diverse agro-wastes, enzymes, and pigments of biological origin. It is envisaged that the compendium will bring to the fore the emerging importance of these bio-resources for nanobiotechnological applications.

Silver‐gold alloy nanoparticles biofabricated by fungal xylanases exhibited potent biomedical and catalytic activities

“…Metallic nanoparticles are extensively acknowledged owing to their widespread range of applications such as antimicrobial, electronics, optics, catalysis, and construction of nanodevices . Among numerous metallic nanoparticles, both silver (AgNPs) and gold (AuNPs) have been broadly studied for their abundant applications due to exceptional resonance, optical, and chemical characteristics .…”

“…[22][23][24][25][26][27][28][29] There are outstanding reviews on the use of pigments, agrowastes, enzymes, arthropods, and their metabolites for the ecofriendly and benign synthesis of nanoparticles. 25,30 Nanomaterials synthesized by means of green synthesis have been well proficient for their noteworthy fungicidal, insecticidal, parasiticidal, mosquitocidal activities apart from their antibacterial activities.

Novel biosynthesized silver nanoparticles from cobweb as adsorbent for Rhodamine B: equilibrium isotherm, kinetic and thermodynamic studies

“…This might not be unconnected with their methods of preparation which are chemical/reduction methods (Patlolla et al 2010). To avoid toxicities arising from physical and chemical-based synthetic routes, green (biological) synthesis of nanoparticles which does not involve the use of hazardous chemicals provides effective route for non/less toxic and ecofriendly nanoparticles (Vanaja et al 2014;Adelere and Lateef 2016;Lateef et al 2016d, e;Pavya et al 2016;Shukla and Iravani 2017).…”

Silver nanoparticles (AgNPs) biosynthesized using pod extract of Cola nitida enhances antioxidant activity and phytochemical composition of Amaranthus caudatus Linn

“…Chemical method of synthesis is less eco-friendly and costly compared to biological (green) synthesis. Green synthesis of nanoparticles offers better advantages to other synthetic routes through the biofabrication of biocompatible, less toxic and eco-friendly nanoparticles (Hasan 2015;Adelere and Lateef 2016;Azeez et al 2016;Lateef et al 2016e, f;Pavya et al 2016).…”
