Synthesis and Determination Extinction Coefficient of Gold Nanoparticles with Different Sizes and Different Capping Ligands

Synthesis and Determination Extinction Coefficient of Gold Nanoparticles with Different Sizes and Different Capping Ligands

Extinction coefficients of gold nanoparticles with different sizes were determined by Zetasizer particle analyser and UV ndash;vis absorption spectroscopic measurement. Four different types of gold nanoparticles were prepared and studied: citrate-stabilized nanoparticles in two different sizes; ionic liquid-protected gold nanoparticles and CTAB-protected gold nanoparticles. A linear relationship between the logarithms of extinction coefficients and core diameters of gold particles was found ...

In silico determination and validation of oprL structure and b cell epitopes as vaccine candidate in Pseudomonas aeruginosa

Pseudomonas aeruginosa is an opportunistic, non-fermentative, gram-negative rod which is an important cause of nosocomial infection leading to septicemia and death. The mortality rate is higher than bacteremias caused by other gram-negative opportunistic pathogens. One of the most important features of the bacterium is its resistance to various antibacterial agents, and even newly developed antibiotics have failed to reduce the mortality rate associated with this organism. There is increasing ...
