“…Preparation of Gold Nanoparticles (AuNPs):-Gold nanoparticle were prepared by reduction of sodium citrate method as mentioned where [17,18] with some slight modifications as follow: gold (III) chloride stock solution (1%) used to prepare 15mM, 20mM and 25mM respectively, followed by heating to 95 o C under stirring on magnetic stirrer with heater. To this boiling solution add tri sodium citrate (1.5% w/v), and continue stirring until give red colour.…”

A new contrast agent in medical imaging discovered and developed since 10 years ago and it's under study until this moment because the classic contrast agents impose earnest limitations on medical imaging abilities such as the short imaging time, poor contrast X-ray images for obese patients (over weighted patients) and real side effects renal problems and toxicity problems. The new contrast agent is the Gold Nanoparticles (GNP) may overcome these restrictions due to its properties where the (GNP) bio distribution is higher than tri-iodobenzene compounds. also, bone /tissue interference is more clear and obvious than tri-iodobenzene compounds and in general nanoparticles clear the blood slowly than classic contrast agents which permit for longer imaging time and all of that leads to enhancing the X-ray diagnostic. Gold Nanoparticles were injected intraperitoneally into mice then images were taken by conventional X-RAY unit. Tumors were seen clearly.

“…2(b)] shows that the particles are almost spherical in shape with a size distribution from 9.5 to 17.50 nm as has also been reported by previous researchers. (34,35) The SPE modified with the AuNPs/ionophore was also characterized by Fourier transform infrared spectroscopy (FTIR). As shown in Fig.…”

, river water, tap waterIn this study, a screen-printed electrode (SPE) was modified with gold nanoparticles (AuNPs) and an ionophore (AuNPs/ionophore/SPE) to provide an electrochemical sensor for the sensitive and selective determination of lead ions using linear sweep anoding stripping voltammetry (LSASV). The effect of electrochemical parameters, including supporting electrolyte, pH, deposition potential, deposition time, and scan rate, on the sensitivity of the sensor for the detection of Pb . The method was used to determine Pb 2+ ions in river and tap water with satisfactory results. The modified electrode displayed benefits such as high sensitivity and selectivity, long time stability, easy preparation, and wide linear range.
