“…There are also many more techniques of synthesizing silver nanoparticles, such as thermal decomposition in organic solvents [18], chemical and photoreduction in reverse micelles [19,20], spark discharge [21], and cryochemical synthesis [22] which yielded nanoparticles between the ranges of 5 to 80 nm in diameter.…”

Silver nanoparticles are nanoparticles of silver which are in the range of 1 and 100 nm in size. Silver nanoparticles have unique properties which help in molecular diagnostics, in therapies, as well as in devices that are used in several medical procedures. The major methods used for silver nanoparticle synthesis are the physical and chemical methods. The problem with the chemical and physical methods is that the synthesis is expensive and can also have toxic substances absorbed onto them. To overcome this, the biological method provides a feasible alternative. The major biological systems involved in this are bacteria, fungi, and plant extracts. The major applications of silver nanoparticles in the medical field include diagnostic applications and therapeutic applications. In most of the therapeutic applications, it is the antimicrobial property that is being majorly explored, though the anti-inflammatory property has its fair share of applications. Though silver nanoparticles are rampantly used in many medical procedures and devices as well as in various biological fields, they have their drawbacks due to nanotoxicity. This review provides a comprehensive view on the mechanism of action, production, applications in the medical field, and the health and environmental concerns that are allegedly caused due to these nanoparticles. The focus is on effective and efficient synthesis of silver nanoparticles while exploring their various prospective applications besides trying to understand the current scenario in the debates on the toxicity concerns these nanoparticles pose.

“…However, the concentration and morphology of these AgNPs are inconsistent since they are dependent on many parameters such as number of laser shots, wavelength of the laser, laser fluence, liquid medium, and ablation time duration [27,28]. Another chemical-free method for AgNP synthesis involves the application of an electrical current between two silver wires in deionized water causing surface silver atoms to evaporate and condense back into aqueous AgNPs [29]. Without the use of chemicals, there are no toxic residuals or contaminations.…”

The invited review covers different research areas of silver nanoparticles (AgNPs), including the synthesis strategies of AgNPs, antimicrobial and anti-inflammatory properties of AgNPs, osteoconductive and osteoinductive activities of AgNP-based materials, and potential toxicity of AgNPs. The potential mechanisms of AgNP's biological efficacy as well as its potential toxicity are discussed as well. In addition, the current development of AgNP applications, especially in the area of therapeutics, is also summarized.

“…Recently, systematic studies have reconfirmed the effective antimicrobial activity of silver [16][17][18][19][20][21]. In this regard, researchers strongly desire to renew the bactericidal application of silver, because of the evolution of new strains of bacteria that are resistant to current antibiotics [22].…”

The effect of an electric field on the antibacterial activity of columnar aligned silver nanorods was investigated. Silver nanorods with a polygonal cross section, a width of 20-60 nm and a length of 260-550 nm, were grown on a titanium interlayer by applying an electric field perpendicular to the surface of a Ag/Ti/Si(100) thin film during its heat treatment at 700• C in an Ar+H 2 environment. The optical absorption spectrum of the silver nanorods exhibited two peaks at wavelengths of 350 and 395 nm corresponding to the main surface plasmon resonance bands of the one-dimensional silver nanostructures. It was found that the silver nanorods with an fcc structure were bounded mainly by {100} facets. The antibacterial activity of the silver nanorods against Escherichia coli bacteria was evaluated at various electric fields applied in the direction of the nanorods without any electrical connection between the nanorods and the capacitor plates producing the electric field. Increasing the electric field from 0 to 50 V cm −1 resulted in an exponential increase in the relative rate of reduction of the bacteria from 3.9 × 10 −2 to 10.5 × 10 −2 min −1 . This indicates that the antibacterial activity of silver nanorods can be enhanced by applying an electric field, for application in medical and food-preserving fields.
