Analysis of the Optical Properties of Silver Nanoparticles

Chitosan/carboxymethyl cellulose wound dressings supplemented with biologically synthesized silver nanoparticles from the ligninolytic fungus Anamorphous Bjerkandera sp. R1

“…When the frequency of the light wave and the intrinsic frequency of the collective electron oscillations in Ag NPs coincide, an increase in scattering resonance and light absorption occurs [39,40]. Regarding this, previous studies have shown that the intensity and shape of the absorption band (SPR) can give insight into different properties of AgNPs, including size, dielectric constants, shape, the amount synthesized in solution and the interaction between them [40][41][42][43] By considering that within the SN suspension there was a rightward shift (red offset) at the maximum wavelength at the SPR peak (425 nm) (Figure 1.b) with respect to the CS suspension (400 nm) (Figure 1a), and significantly decreased the absorbance, it can possibly be inferred that within the SN sample, the size of AgNPs increased and there was a lower concentration of them within the suspension [39,44,45]. The decrease in absorption peak intensity is caused by a decrease in the concentration of Ag NPs.…”

A review on acceptability of denture polymers having gold and silver nanoparticles

“…These form the SRP band (Surface Plasmon Resonance). The position of the maximum, the shape and the intensity of AgNPs' absorption band depend on their size, shape and properties of the surrounding liquid medium [38]. The smaller the particle size, the shorter the wavelength and weaker absorption spectra [37].…”

Kinetic and Mechanistic Studies of the Formation of Silver Nanoparticles by Nicotinamide as a Reducing Agent

“… 8 , 9 We have mainly focused on 0D inorganic nanomaterials, i.e., metal or metal oxide nanoparticles, 9 , 10 because of their high surface area to volume ratio, sharp size distribution in the range of 1–100 nm, and uniformity in their shape. 11 Nanoparticles in the elemental form of metals, especially of Ag, Au, Fe, Cu, Pt, Pd, Ni, and Co, have been widely used for their antimicrobial, 12 − 14 optical, 10 , 15 catalytic, 16 − 18 electronics, 19 , 20 and sensing 21 properties and also as doping agents. 22 Nanoparticles have also been employed in different fields such as health care, 23 cosmetics, 24 food industries, 25 environmental remediation, 26 optics, 15 biomedical sciences, 27 chemical industries, 28 electronics, 19 , 20 drug delivery, 29 energy science, 30 optoelectronics, 31 catalysis, 16 − 18 etc.…”

“…Currently, inorganic nanomaterials including zero-dimensional (OD), , one-dimensional (1D), , two-dimensional (2D), − and three-dimensional (3D) materials have attracted increasing attention due to their physicochemical properties being different from those of their bulk part. , We have mainly focused on 0D inorganic nanomaterials, i.e., metal or metal oxide nanoparticles, , because of their high surface area to volume ratio, sharp size distribution in the range of 1–100 nm, and uniformity in their shape . Nanoparticles in the elemental form of metals, especially of Ag, Au, Fe, Cu, Pt, Pd, Ni, and Co, have been widely used for their antimicrobial, − optical, , catalytic, − electronics, , and sensing properties and also as doping agents .
