Antimicrobial Studies Of Silver Nanoparticles And Silver Lab Report
Synthesis, Spectral, and Antibacterial Studies of Silver Nanoparticles and Silver(I) Complex of 2-Mercaptobenzothiazole
Abstract :
Microbes, such as bacteria, molds, yeasts, and viruses, in living environment are often pathogenic and cause severe infections in human beings. Therefore, there is a pressing need to search for new antimicrobial agents from natural and inorganic substances [1]. Antimicrobial nanoparticles mainly consist of metals, metal oxides, and many biologically derived materials. [2].Its antimicrobial activity is associated with the characteristic structure of nanoparticles [3].The effective antimicrobial properties of these materials are mainly due to their nano size providing them unique chemical and physical properties …show more content…
160 A-Ultra-violet spectrophotometer in the range (200-1000) nm. Atomic absorption measurements of the prepared complex were obtained using Shimadzu 680cc-flame. The magnetic susceptibility values were obtained at room temperature using Magnetic Susceptibility Balance Bruke Magnet B.M.6. The 1H and 13C nuclear magnetic resonance spectra were recorded on a jeol 400 MHz spectrometer in dueteated DMSO, relative to the internal standard Tetramethylsilane (TMS). Conductivity measurements were carried out by using a WTW conductivity meter .
Synthesis of Ag (I) complexes
A solution of (2.5 mmole) of AgNO3 dissolved in 50 ml of water was added drop by drop to (10 mmole) of ligan dissolved in 80 ml of absolute ethanol. The mixture was stirring for 15 min the resulting precipitate was filtered off washed with distilled water then dried under vacuum, the physical properties of the prepared complexes listed in Table
