Gold Nanoparticle Colloidal Solution 
Bio films living on gold (Au) grains play a key role in the biogeochemical cycle of Au by promoting the dispersion of Au via the formation of Au nanoparticles as well as the formation of secondary biomorphic Au. It consists of a bacterial biofi lm containing Au nanoparticles associated with extracellular polymeric substances as well as bacterioform Au.

Applications because of their unique characteristics such as catalytic activity, optical, electronic thermal, magnetic and other properties. In particular, gold nanoparticles are currently being explored for example in catalysis, chemical sensing, molecular labeling, gene delivery, and photonics.

Gold Nanoparticle Colloidal Solution, 
The synthesis of colloidal solutions of gold nanoparticles (AuNPs) dispersed in castor oil. These colloids were prepared via a wet chemistry process by mixing specific amounts of castor oil, ethanol, and aqueous solutions of tetrachloroauric(III) acid and sodium hydroxide. The size and shape of the AuNPs obtained could be modulated by the amount of gold source added and the Au/OH– molar ratio used. The free fatty acid content in the reaction medium was an important parameter to be considered in the syntheses of the colloidal solutions and the respective form and shape of the AuNPs produced. Thus, we evaluated the effect of oil acidity by adding different amounts of myristic acid (MA) in the reaction medium.

Gold Nanoparticle Colloidal Solution, 
Metal nanoparticles are presently used in a wide range of applications such as catalysis, optical labeling, ferrofluids, and sensing. These applications, along with the recent attention to nanoscale science and technology, fuel the demand for methodologies which enable nanoparticles to be incorporated into nanostructured devices and composite materials. Dispersing metal particles in nonpolar organic solvents is appealing because the low interfacial energie should allow for a high degree of control during solution and surface processing.

Gold Nanoparticle Colloidal Solution based catalysts and impregnation to incipient wetness imbibitions, deposition-precipitation and deposition/immobilization of colloidal gold on are the most commonly used. Gold catalytic performance depends strongly on a combination of parameters: morphology, dispersion, metal particle size, temperature Ph and interactions b/w gold particles material.
