Silver nanoparticles: Synthesis methods, bio-applications and properties

Abstract

Silver nanoparticles size makes wide range of new applications in various fields of industry. Synthesis of noble metal nanoparticles for applications such as catalysis, electronics, optics, environmental and biotechnology is an area of constant interest. Two main methods for Silver nanoparticles are the physical and chemical methods. The problem with these methods is absorption of toxic substances onto them. Green synthesis approaches overcome this limitation. Silver nanoparticles size makes wide range of new applications in various fields of industry. This article summarizes exclusively scalable techniques and focuses on strengths, respectively, limitations with respect to the biomedical applicability and regulatory requirements concerning silver nanoparticles.

Microwave-assisted green synthesis and antimicrobial activity of silver nanoparticles derived from a supercritical carbon dioxide extract of the fresh aerial parts of <i>Phyllanthus niruri</i> L

“…The synthesis of AgNPs can be achieved by different physical as well as chemical methods like chemical reduction, UVirradiation, photochemical method, electron irradiation and recently by biological routes from microorganisms, enzymes and plant extracts. The biological method has shown an advantage over other methods due to its low cost, environmentally friendly, easy synthesis on a large scale [3,4]. Numerous research articles on the synthesis of AgNPs from the plant extracts have been published in the last decade that clearly highlights their therapeutic potential.…”

Insight into eco-friendly fabrication of silver nanoparticles by Pseudomonas aeruginosa and its potential impacts

“…Silver nanoparticles (AgNPs) have garnered much attention due to the wide range of applications in catalysis 1 , membrane bioreactors 2 , DNA sequencing 3 and cancer treatment 4 . Several physical and chemical strategies have been employed for the production of nanoparticles (NPs) 5 . Conventional synthesis procedures are becoming obsolete due to the high cost 6 , hazardous nature 7 , and low yield 8 .…”

Optical and Photoacoustic Properties of Colloidal Silver Nanoparticles Solutions

“…The photoacaustic imaging technique was employed for using biomedical science (Oraevsky, Jacques & Tittel, 1997;Kruger, 1994;Ku et al, 2005;Wang et al, 2002). Properties of silver nanoparticles can also be used in the wide range of different field of integrated circuits, biosensors, medical imaging, drug delivery, hyperthermia therapy, chemosensors, electrochemical sensors, bio labeling, and filters because of exhibiting an antibacterial activity as well as surface plasmon resonance (Pal, Tak, & Song, 2007;Abbasi et al, 2016;Amendola & Meneghetti, 2009;Fukasawa et al, 2014;Schröfel et al, 2014). In addition, many pure metals-based nanoparticles emerge unusual properties that have discussed optical, electrical, and magnetic properties (Chen et al, 2009;Garitaonandia et al, 2008;Hao & Schatz, 2004;Mock et al, 2002;Sun, & Xia, 2002).…”
