“…Proper to their small size, nanoparticles have a high surface to volume ratio, this increases the surface energy compared with that of bulk materials. The high surface to volume ratio together with the size effect gives nanoparticles discriminative different properties (chemical, optical, electronic and magnetic) from those of bulk material [1][2][3][4][5]. Different preparation methods have been reported for the preparation of metal oxide nanoparticle, notable examples comprise, laser ablation, gamma irradiation , electron irradiation , chemical reduction , photochemical methods, microwave processing, and biological synthetic methods [6].…”

Silver nanoparticles (Ag-NPs) have been prepared using the electro-chemical method. The experimental setup of this technique consist of two electrodes of pure silver (99.2 %), the applied voltage on the electrodes is 20 V and the current through the colloidal was about 0.4 Amp. The silver nanoparticles crystallization has been studied; the crystalline structure appears Face center Cubic. The optical properties of silver nanoparticles are strongly affected by the Local Surface Plasmon Resonance (LSPR). The wavelength of maximum absorption band for an Ag NPs have a range (~350nm-550nm).Keywords: Ag nanoparticle, electrochemical method, surface Plasmon resonance, EDX test. ‫الغروية‬ ‫النانوية‬ ‫الجسيمات‬ ‫الفضة‬ ‫لسائل‬ ‫السطح‬ ‫بالزمون‬ ‫رنين‬ ‫اسة‬ ‫در‬

“…These particles showed great possibilities in malignant condition as mediator in chemotherapeutic doses delivery and targeting tumor cell. Synthesis of metallic nanoparticles is carried out by several physical and chemical methods that include laser ablation [13], ion sputtering [14], solvo thermal synthesis [15], chemical reduction [16], and sol-gel [17,18] method, involve toxic solvents, high temperature, energy and high pressure conversion. Few studies held, were focused on Microbe mediated synthesis as of not practical for industries due to laboratory maintenance.…”

In present study, copper oxide nanoparticles (CuONPs) synthesized by quick and eco-friendly phytogenicreduction of copper salt (copper sulphate CuSO 4 .H 2 O) solution with Pterocarpus marsupium extract. UV-VIS spectrometry indicated formation of nanoparticles via absorption spectra of copper colloidal solution at 442 nm. Phytosynthesis of CuONPs were further characterized by Transmission electron microscopy; scanning electron microscopy and Fourier transform infrared spectroscopy. The experimental results showed that diameter of CuONPs in colloidal solution were < 40 nm. Further, antibacterial activities of CuONPs were determined against Gram negative Escherichia coli-MTCC-9721, Proteus vulgaris-MTCC-7299, Klebsiella pneumonia-MTCC-9751 and Gram positive i.e. Staphylococcus aureus-MTCC-9442, Staphylococcus. epidermidis-MTCC-2639, Bacillus cereus-MTCC-9017 bacteria by well agar diffusion and microdilution method. Notably, The CuONPs showed an effective antibacterial activity against all test microorganisms where K. pneumonia and E.coli showed maximum ZOI and MIC respectively i.e. 24 mm and 6 μg/ml.

Aggregation state of silver nanoparticles dispersed in an aqueous solution greatly varies with storage and treatment conditions. In this study, silver nanoparticles synthesized in chitosan solution by a chemical reduction method were hydrothermally treated at different temperatures. The variation in the aggregation state of silver nanoparticles in the solution was observed by UV-Vis spectroscopy and field emission transmission electron microscopy. Results indicated that a phase transition occurred while silver nanoparticles were hydrothermally treated for 5 h at 100 and 120 ∘ C; however, they aggregated and completely precipitated at 150 ∘ C. Mesoporous silver powder obtained by hydrothermal treatment at 150 ∘ C was characterized by using X-ray diffraction technique, BET analyzer, and scanning electron spectroscope.
