Rapid green synthesis of silver nanoparticles by aqueous extract of seeds of Nyctanthes arbor-tristis

Abstract

The present study explores that the aqueous extract of the seeds of Nyctanthes arbor-tristis (aka night jasmine) is very efficient for the synthesis of stable AgNPs from aqueous solution of AgNO 3 . The extract acts as both reducing (from Ag ? to Ag 0 ) and capping agent in the aqueous phase. The constituents in extract are mainly biomolecules like carbohydrates and phenolic compounds, which are responsible for the preparation of stable AgNPs within 20 min of reaction time at 25°C using without any severe conditions. The synthesized silver nanoparticles were characterized with UV-Visible spectroscopy, FT-IR, XRD and SEM. UV-Vis spectroscopy analysis showed peak at 420 nm, which corresponds to the surface plasmon resonance of AgNPs. XRD results showed peaks at (111), (200), (220), which confirmed the presence of AgNPs with face-centered cubic structure. The uniform spherical nature of the AgNPs and size (between 50 and 80 nm) were further confirmed by SEM analysis.

A Review of Silver Nanoparticles: Research Trends, Global Consumption, Synthesis, Properties, and Future Challenges

“…The resulting AgNPs sizes were below 100 nm. In another study, the use of the extract from the seeds of Nyctanthes arbor‐tristis as the reducing and capping agent to synthesize AgNPs was explored . The study was carried out at room temperature.…”

Systemic Review on Anti-Sciatica Plant “Night Jasmine” (Nyctanthes arbortristis Linn.)

“…The seed is compressed and is 1 per cell (Abhishek Kumar Sah and Vinod Kumar Verma, 2012) Seeds are exalbuminous, test thick; the outer layer of large transparent cells and heavily vascularised (Bhosale et al, 2009) phytosterols, phenolics compounds, tannins, flavonoids, cardiac glycosides, saponins and alkaloids all are found in seeds of N. arbortristis (Shibani Basu et al, 2016).…”

Polyol Silver Nanowire Synthesis and the Outlook for a Green Process

“…The variety of metal nanoparticles that have been produced illustrate the various biochemical and physiochemical properties that enable novel technologies and devices [12]. Among these, silver nanoparticles (AgNPs) have unique and outstanding shape-and size-dependent electrical, thermal, optical, catalytical, optoelectronic, anticancer, biosensing, medicinal, antiviral, and biological characteristics which make them exceptional for several applications in a variety of fields and disciplines such as dentistry, drug delivery, biomedical, anticancer, antimicrobial, antioxidant, food science, agriculture, cosmetic, clothing, water treatment, larvicides, forensic science, pollution control, waste management, and photovoltaics [12][13][14][15][16][17][18][19][20][21]. Silver has an inhibitory activity toward several microorganisms and bacterial strains and can be used in arthroplasty, medicine, and to prevent bacterial colonization [22].…”
