Shora (Capparis petiolaris) fruit mediated green synthesis and application of silver nanoparticles

Abstract

This report describes a rapid, facile and an ecofriendly synthesis of silver nanoparticles (AgNps) using fruit extracts of Shora (

Synthesis and Characterization of Silver Nanoparticles Prepared with Carrasquilla Fruit Extract (Berberis hallii) and Evaluation of Its Photocatalytic Activity

“…Results demonstrate that both types of AgNPs are linked to the crystalline planes of face centered cubic (fcc) structure of the silver metal and closely correlates to the reported reference values of the Joint Committee on Powder Diffraction Standards (JCPDS PDF no: 89-0713). These peaks are similar to those nanoparticles prepared by green synthesis using Shora [10], Rosa hybrida petal [30], cochineal [31] extracts. The remaining diffraction peaks at 2θ = 28.23 • , 31.54 • , 40.44 • , and 64.32 • for the AgNPs synthesized with 1mM AgNO 3 solution and 2θ = 27.58 • , 32.02 • , and 37.93 • for the AgNPs synthesized with 10 mM AgNO 3 solution, are difficult to directly attribute to the correspondent silver phase.…”

“…Several weights of the dry extract were dissolved in distilled water (10,20,40, 60 mg/mL). One milliliter of each concentration at pH of 7.5, 9.5 or 12.5 was added to 10 mL of 1 m or 10 mM of silver nitrate solution (AgNO3) contained in falcon tubes and incubated for 1 h in a water bath at 40 °C to complete the synthesis.…”

“…These phyto extracts are the reducing agents that promote the formation of nucleation centers and the incorporation of neighboring sites into the nucleation to produce different morphologies of nanoparticles [8,9]. Multiple studies have been carried out with fruits such as Capparis petiolaris [10], Terminalia chebula [8], Passiflora tripartite [11] to demonstrate the formation of nanoelements. Plants are a natural source of secondary metabolites like flavonoids that are responsible for the red, purple, and blue colors of flowers and leaves [12].…”

“…Plants are a natural source of secondary metabolites like flavonoids that are responsible for the red, purple, and blue colors of flowers and leaves [12]. It is well known that plant extracts are economic resources that do not generate by-products in the environment [4,5,[7][8][9][10][11] so they are being used more often in the fabrication of nanostructures. The Carrasquilla (Berberis hallii) fruit of the Berberidaceae family found in the highlands of the Andes at an altitude of 2400 m, is a black-purple spherical drupe and is used as a food for birds [13,14].…”

Green Synthesis of Gold, Silver, and Iron Nanoparticles for the Degradation of Organic Pollutants in Wastewater

“…It has shown that the sunlight irradiation step is more useful compared to other parameters such as pH, concentration, or temperature for the synthesis of silver nanoparticles. Furthermore, the synthesized nanoparticles showed photocatalytic activity and are well fitted by a first-order rate law for the degradation of MB (>58%, k = 0.0025293163 min −1 ) [56]. Arunachalam et al (2012) presented a Coccinagrandis leaf extract-mediated bioreductive synthesis of 20-30 nm-sized Ag particles and demonstrated the use of an ecofriendly and low-cost biological reducing agent to generate metallic nanoparticles.…”
