Raspberry Extract as Both a Stabilizer and a Reducing Agent in Environmentally Friendly Process of Receiving Colloidal Silver

Abstract

An ecofriendly method of nanosilver obtaining has been studied. The process involves the chemical reduction method carried out in aqueous environment. Silver nitrate (V) was applied as a silver ions source. Raspberry extract was used as a natural source of both reducing and stabilizing agents. The total amount of phenolic compounds was determined by the Folin-Ciocalteu method. Obtained nanoparticles were analyzed by the dynamic light scattering technique so as to determine the particles size and suspension stability which was characterized by an electrokinetic potential. The results confirmed that the size of some nanoparticles was under 100 nm.

Green Silver Nanoparticles Formed by Phyllanthus urinaria, Pouzolzia zeylanica, and Scoparia dulcis Leaf Extracts and the Antifungal Activity

“…Previously, diverse plants have been investigated regarding forming silver nanoparticles [19][20][21]. More than sixty plants used for green AgNP synthesis were summarized [11,14], but Phyllanthus urinaria (P. urinaria), Pouzolzia zeylanica (P. zeylanica), and Scoparia dulcis (S. dulcis) are plants of interest that have not yet been explored.…”

The effect of fish collagen on the silver nanoparticles sizes and shapes using modified microwave-assisted green synthesis method and their antibacterial activities

“…The nanosilver with potential anticancer action has been synthesized using the Indian Melia dubia extract using AgNO 3 . Kathiravan et al [ 5 ] have produced AgNPs with anticancer properties.According to previous studies, a wide range of stabilizers was used to cap the AgNPs, such as gelatin [ 6 ], polyvinylpyrrolidone (PVP) [ 7 ], and poly(vinyl alcohol) [ 8 ]. Many of these studies used a chemical stabilizer that may cause toxicity for the final product.…”
