Synthesis of quercetin-functionalized silver nanoparticles by rapid one-pot approach
Nanotechnology plays a pivotal role in all areas of science, and the synthesis and surface modification of nanoparticles are crucial in this field. Metal nanoparticles synthesized using plant extracts or phytocompounds are highly significant in the development of various therapeutics and diagnostics. In the present study, we report the one-pot and rapid synthesis of silver nanoparticles (AgNPs) by quercetin, a flavonoid found in various edible plants. The nanoparticles were then characterized using UV-VIS spectrophotometry, Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The role of quercetin in the synthesis of silver nanoparticles was demonstrated. The nanomaterial was 20–30 nm in size and spherical in shape. The silver nanoparticles were also confirmed to show antioxidant activity at 80 μg/ml concentration in vitro by DPPH, FRAP, and power reduction methods

Biological synthesis of metallic nanoparticles: plants, animals and microbial aspects
The green synthesis (GS) of different metallic nanoparticles (MNPs) has re-evaluated plants, animals and microorganisms for their natural potential to reduce metallic ions into neutral atoms at no expense of toxic and hazardous chemicals. Contrary to chemically synthesized MNPs, GS offers advantages of enhanced biocompatibility and thus has better scope for biomedical applications. Plant, animals and microorganisms belonging to lower and higher taxonomic groups have been experimented for GS of MNPs, such as gold (Au), silver (Ag), copper oxide (CuO), zinc oxide (ZnO), iron (Fe2O3), palladium (Pd), platinum (Pt), nickel oxide (NiO) and magnesium oxide (MgO). Among the different plant groups used for GS, angiosperms and algae have been explored the most with great success. GS with animal-derived biomaterials, such as chitin, silk (sericin, fibroin and spider silk) or cell extract of invertebrates have also been reported. Gram positive and gram negative bacteria, different fungal species and virus particles have also shown their abilities in the reduction of metal ions. However, not a thumb rule, most of the reducing agents sourced from living world also act as capping agents and render MNPs less toxic or more biocompatible. The most unexplored area so far in GS is the mechanism studies for different natural reducing agents expect for few of them, such as tea and neem plants. This review encompasses the recent advances in the GS of MNPs using plants, animals and microorganisms and analyzes the key points and further discusses the pros and cons of GS in respect of chemical synthesis.Fil: Das, Ratul Kumar.
