Preparation of amine coated silver nanoparticles using triethylenetetramine

Abstract

This article presents a simple method towards the preparation of functionalized silver nanoparticles in a continuous medium. Silver nanoparticles were obtained through AgNO 3 chemical reduction in ethanol and triethylenetetramine was used to stabilize and functionalize the metal. The product was characterized with X-ray diffraction (XRD), Fourier-transformed infrared spectroscopy (FTIR), UVvisible spectroscopy, thermal gravimetric analysis (TGA) and transmission electron microscopy (TEM). Monocrystalline silver particles with cubic structure and an average size of 20 nm were obtained. The results reveal that it is possible to synthesize Ag nanoparticles functionalized with amine groups and that particle size is influenced by the processing route.

Eco-friendly synthesis of silver nanoparticles using leaf extract of Flemingia wightiana: spectral characterization, antioxidant and anticancer activity studies

“…The market of AgNPs have been increased year to year due to their vast usage in the industries related to food packaging, wound dressings, diagnostic kits and other medical equipments [23][24][25]. Different chemical and physical methods including thermal decomposition [26], laser ablation [27], electrochemical [28], photochemical [29], sonochemical [30], gamma-irradiated [31], ultrasound assisted [32], polyaniline [33], chemical reduction [34], and lithography [35] methods have been successfully reported for the preparation of AgNPs. But these methods employ radiations and toxic chemicals.…”

Characterizations and analysis of the antioxidant, antimicrobial, and dye reduction ability of green synthesized silver nanoparticles

“…Among all, silver nanoparticles are the most efficient because they have a strong antimicrobial effect on fungus [12], bacteria [13], and other eukaryotic microorganisms, as theranostic [6] and antitumor agents [14]. Owing to exceptional characteristics such as excellent catalytic properties, conductivity, antibacterial activity, and chemical stability, colloidal silver is of specific interest [15]. Different procedures used for manufacturing nanoparticles frequently involve toxic, reducing agents and chemical solvents/surfactants [16][17][18], which typically produce a bulk amount of lethal wastes [19].…”

Silver Nanoparticles as a New Solid-Phase Adsorbent and Its Application to Preconcentration and Determination of Lead from Biological Samples

“…Among these materials, metallic nanoparticles have been widely investigated for use in nanoscale devices which bind biological materials [12][13][14]. Organic monolayer-protected metal nanoparticles are particularly attractive for their chemical stability and quantitative control of multiple functionalization [15][16][17][18]. Therefore, the stabilized silver nanoparticle as adsorbents was used for preconcentration of lead.…”
