Green chemistry methods for production of nanoparticles have many advantages, such as ease of use, which makes the methods desirable and economically viable. The aim of the present work was to green synthesise silver nanoparticles (SNPs) using aqueous tangerine peel extract in different ratios (2:1, 1:1, 1:2). The formed SNPs were characterised using ultraviolet-visible (UV-Vis) spectrophotomet...

background the production of nanoparticles using a biosystem is considered green chemistry. application of plant extracts as a biological process has been proven to be suitable for synthesis of nanoparticles. objectives this study designed in order to evaluate the production of silver nanoparticles using juglans regia leaf extract and to compare the outcome of different preparation methods of p...

A completely green synthesis protocol has been adopted to obtain silver nanoaggregates capped by the natural compound (1E, 6E)-1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-diene), also known as curcumin. The synthesis has been monitored by infrared, Raman, visible and fluorescence spectroscopies. Characterization confirms that curcumin reduces and caps the nanoparticles, and such a pro...

Silver nano-particles have different biological applications due to their compatibility. Chemical methods usually result in remaining some amounts of toxic reactions on the nano-particles. For this reason, the use of plants as sustainable and accessible resources in preparation of compatible nano-particles has attracted a lot of attention in the recent years. This research investigated the gree...

Textile materials are good carriers of various types of micro organisms and can cause health related problems to the wearer. Application of natural antimicrobial agents on textile dates back to antiquity, when the ancient Egyptian used. Herbs were used to inhibit the growth of bacteria on textiles. Silver is a renowned antimicrobial agent used on textiles from very ancient time till date. A ver...

Among various natural sources, plant materials are t...

The purpose of this study was to expand a trouble free biological method for the synthesis of silver nanoparticles (AgNPs) using the leaves extract of Rosa ChinensisL. to act as reducing and stabilizing agent. Water soluble phytochemicals played a vital role for the reduction silver ions into silver nanoparticles. The leaves extract was exposed to silver ions and the resultant biosynthesized Ag...

In this study, a single-step method for green synthesis of silver nanoparticles usingAloe Vera gel extract and sunlight was investigated. The Aloe Vera gel extractis composed of pectins, lignin, and hemicellulose, which can be used in thereduction of silver ions to produce colloidal silver nanoparticles (AgNPs-AV). Thepreliminary preparation of silver nanoparticles was o...
