“…The LSPR spectra exhibited shifting to larger wavelength or red-shift as the size of Ag-NPs and the thickness of PVA increased. Similar observations were also reported by Ananth [6] and Mbhele [17]. The red-shift phenomenon of the LSPR Ag-NPs was simply can examined by scattering [18].…”

“…To maintain the stability of the Ag-NPs for practical purpose, usually Ag-NPs combined with some polymeric composites such as polyvinyl alcohol (PVA), polypyrrole (PPy), carbonxymethyl cellulose (CMC) [3,4], biocompatible moleculessuch as bovine serum albumin (BSA) [5,6] and semiconductor such assilica [7]. Numerous studies have been also reported in numerical approximation to investigate the LSPR spectra, such as determining the interaction between Ag-NPs and PVA using density functional theory (DFT) to calculate the binding energy [8], finite different time domain (FDTD)method to produce the LSPR spectra Ag-NPs nanocubes [9], and the calculation the scattering intensity in the nanoshell model [10,11].…”

In this study, we have investigated the LSPR spectra of the silver nanoparticles (Ag-NPs) coatedby polyvinyl alcohol (PVA) by means of a numerical study using Bohren-Huffman-Mie (BHMie) approximation. The LSPR of Ag-NPs shifted to red-shift as the diameter size of Ag-NPs and the thickness of PVA increased. The peak of the LSPR spectra exponentially increased as the thickness increased. Interestingly, there have three characteristic of the LSPR spectra, small, intermediate, and large diameter. In small diameter, the dipole resonant mode contributed to the LSPR spectra while in large diameter, the LSPR spectra originated from the quadrupole resonant mode. In contrast to intermediate diameter, the LSPR spectra originated from the competition between the dipole and the quadrupole mode. For this reason, at small and large diameter the LSPR peak has one peak and increased then until a certain thickness showed constant. Different at intermediate diameter, the LSPR peak appeared more one peak with major peak increased then until a certain thickness trend to decrease and minor peak followed at small diameter behavior.

Nanoparticles have comprehensively affected various sights of human life. Through the wide range of claims about nanosized particles and their functions, biomedical applications are of much interest among health care researchers due to the nanoparticles' potential for use in the process of disease diagnosis, control and treatment. In this regard, inorganic nanoparticles, which have high potential in diagnostic and therapeutic systems, have recently received much attention in oncology. Although inorganic nanoparticles initially seemed an appropriate tool for cancer imaging and diagnosis, their ability to attack cancerous cells as anticancer drugs or carriers in other drugs has also demonstrated promising results. The present review primarily provides a brief survey of various studies in which metal nanoparticles such as gold, silver, iron oxide, and metalloid nanoparticles viz. tellurium and bismuth were exploited for therapeutic or diagnostic purposes in oncology. Then the application of selenium nanoparticles as a therapeutic agent against cancer in in vitro and in vivo studies is reviewed in detail. Although inorganic nanoparticles seem to be useful tools for cancer imaging and diagnosis, their potential for attacking cancerous cells as anticancer substances or even carriers for anticancer medications should not be underestimated.

Polyvinyl alcohol (PVA) hydrogels are materials for potential use in burn healing. Silver nanoparticles can be synthesized within PVA hydrogels giving antimicrobial hydrogels. Hydrogels have to be swollen prior to their application, and the common medium available for that in hospitals is saline solution, but the hydrogel could also take up some of the wound's fluid. This work developed gamma-irradiated PVA/nano-Ag hydrogels for potential use in burn dressing applications. Silver nitrate (AgNO 3 ) was used as nano-Ag precursor agent. Saline solution, phosphate-buffered solution (PBS) pH 7.4 and solution pH 4.0 were used as swelling media. Microstructural evaluation revealed an effect of the nanoparticles on PVA crystallization. The swelling of the PVA-Ag samples in solution pH 4.0 was low, as was their silver delivery, compared with the equivalent samples swollen in the other media. The highest swelling and silver delivery were related to samples prepared with 0.50% AgNO 3 , and they also presented lower strength in PBS pH 7.4 and solution pH 4.0. Both PVA-Ag samples were also non-toxic and presented antimicrobial activity, confirming that 0.25% AgNO 3 concentration is sufficient to establish an antimicrobial effect. Both PVA-Ag samples presented suitable mechanical and swelling properties in all media, representative of potential burn site conditions.
