Silver Nanoparticles: Synthesis, Characterization and Applications

Abstract

Day by day augmenting importance of metal nanoparticles in the versatile fields like, catalyst, electronic, magnetic, mechanic, optical optoelectronic, materials for solar cell and fuel cell, medical, bioimaging, cosmetic, ultrafast data communication and optical data storage, etc, is increasing their value. Nanoparticles of alkali metals and noble metals (copper, silver, platinum, palladium, and gold, etc.) have a broad absorption band in the visible region of the electromagnetic spectrum of light, because the solutions of these metal nanoparticles show the intense color, which is absent in their bulk counterparts as well as their atomic level. The main cause behind this phenomenon is attributed to the collective oscillations of the free conductive electrons that are induced by an interaction with electromagnetic field. The whole incidence is known as localized surface plasmonic resonance. Out of these, we have selected the silver nanoparticles for the studies. In this article, we will discuss the synthesis, characterization, and application of the silver nanoparticles. Future prospective and challenges in the field commercialization of the nanosilver is also discussed.

Plasmonic enhancement of betanin-lawsone co-sensitized solar cells via tailored bimodal size distribution of silver nanoparticles

“…This deviation could be because, under experimental conditions, an additional influence of multiple neighboring AgNPs in the chosen environment is expected to have on each other whereas in the simulations only a single AgNP in the chosen environment has been considered. Besides, the simulations use Ag material parameters for the bulk model, though in the nano-scale, the material specifications for AgNPs prepared via solution-processed methods, may slightly differ 87 . The capping agent used for the synthesis could cause result in the broadening of the peaks 88 .…”

Green Chemistry Synthesis of Silver Nanoparticles and Their Potential Anticancer Effects

“…Cancer nanotechnology unfolded a newer horizon of interdisciplinary research across chemistry, medicine, engineering and 2 of 26 biology focusing on the major advancement in cancer detection, diagnosis and treatment [3]. In recent years, nanoparticles (NPs) have gained an immense scientific attraction due to their large surface area to volume ratio and high reactivity with unmatchable properties [4]. Recently, nanotechnology-based anticancer drugs, such as Abraxane ® (Celgene, Summit, NJ, USA), Doxil ® (Johnson & Johnson, New Brunswick, NJ, USA) and Myocet ™ (Perrigo, Dublin, Ireland), have been approved by the US Food and Drug Administration for clinical use [5].…”

Biosynthesis, characterization, and in vitro assessment on cytotoxicity of actinomycete-synthesized silver nanoparticles on Allium cepa root tip cells

“…The physical methods of synthesis produce large quantities of nanoparticles with definite shape and size. However, the production of large quantities of waste materials, uses of high amount of energy, time required for synthesis, and acquiring thermal stability of nanoparticles are the disadvantages of this process [1,8,9]. Chemical methods of synthesizing are complicated and have many effects, such as producing numerous dangerous chemicals, which are toxic in nature and produce wastes.…”
