“…For the influence of AgNPs on human blood; the experiment was conducted on six donner mal health adult. We labeled the samples and the controls (B1-B6) and examined pre and post nano silver particles injecting to blood, urea, blood creatinine, and phosphates of alkaline test by Uv-Vis spectrophotometer (SP-3000 Optima-plus-Chapan) [36,[39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55]. The former was red upper level and yellow color serum lower level.…”

In this paper we demonstrate physical method (Gamma irradiation technique) for synthesizing Ag-NPs when there is no reduction agent or heat treatment as useful in antimicrobial applications and medical devices. As a strong support, stabilizer, and silver precursor, Chitosan (CS) and AgNO3 were utilized. Ag/Cs characteristics were investigated as a function of gamma dose and -irradiation periods in recent published paper. For conducting the research in Ag-CS-Isopropanol (IPA) by gamma Irradiation method, here we used UV-vis spectroscopy for examining energy gap and Plasmon resonance of surface (SPR) of the produced silver nanoparticles (Ag-NPs). Manufactured Ag-NP UV-vis spectroscopy revealed as the gamma dose increased, the highest wavelength intensity of the plasmon peaks rose. and with energy gap in rang (2.1-2.4) eV. The effect of Ag/CS-APA solutions has examined due on human blood properties and antibacterial activity to water samples selected from local riverbank in Iraq. Overall, the optical characteristic of Ag-CS-APA nanocomposite solution make them promising material for optical thin films and as antibacterial agent in health sector.

“…Steel pieces with dimensions of (10.5 x 10.5) cm were prepared [30][31][32][33][34]. After that, the surface was polished and smoothed with polishing papers (grade 400) to prepare the surface to receive the mixture, as well as to clean the surface from any sediments, oxides, dust or dirt, just like preparing the surface for car painters [35][36][37][38][39]. The surface was washed with fresh water, dried for 1 hour, then cleaned with acetone or alcohol, according to what is customary among scientific sources.…”

High-efficiency radar wave absorbing material was prepared utilizing nanoparticles poly (glycerol /phthalic anhydride), and the effect of using these nanocomposites with thermal paint on the properties of electromagnetic absorbing was analyzed and investigated. Results show that when the percentage of nano polymers is increased from 1% to 3%, with the presence of 2.5% of iron oxide, the reflectivity loss value rises dramatically. For the reflectivity up to 27.2dB at a frequency of 8.3 GH and a bandwidth of (8.1-8.2GH), there is a clear attenuation of the radar waves, which is confined within a bandwidth of GH (9-9.3GH). This material can be utilized as a high- efficiency radar wave absorbing applications.

“…A transmission electron microscopy (TEM) and UV-vis spectrophotometer was used to measure the solution's absorption spectrum at 420 nm, which resulted in the confirmation of the nanoparticles production. The particle size was determined using a Hitachi H7100 transmission electron microscopy (TEM) [40][41][42][43] and (UTHSCSghA Image Tool) version 3.00 application to calculate the distributions [44][45][46].…”

The present study demonstrates a green process for the synthesis of spherical-shaped and stabilized silver nanoparticles Ag NPs using gamma irradiated conditions. This method has certain advantages over conventional methods since it can manage the particle size and structure and generates totally reduced and extremely pure nanoparticles free from by-products or chemical reducing agents. Silver nanoparticles composite (Ag NPs / CM) is prepared from an aqueous solution of silver nitrate, chitosan and isopropanol, at room temperature using gamma irradiation doses to induce reduction and cross-linking to formation in situ Ag NPs/ CM-chitosan-isopropanol solutions. The production and homogenous distribution of silver nanoparticles in the hydrogel matrix were characterized using transmission electron microscopy, XRD, Zeta potential and UV-Vis spectrophotometer analysis. The silver/ CM-chitosan-isopropanol matrixes possessed different gamma doses using a Co- 60 gamma source. Through the comprehensive results of IR- Ag NPs /(CM- chitosan isopropanol solutions due to antibacterial activity test, the results show the prepared Ag NPs /CM-chitosan-isopropanol could be used as an antibacterial agent. The obtained Ag nanoparticles were stable for over 3 months at room temperature. the analysis outcomes indicate that the colloidal Solution (silver nanoparticles / (CM chitosan - isopropanol)) has a promising ability to be used in antibacterial applications in the future.
