effects of temperature and percentage of organic modifier were studied on retention and selectivity in rp-hplc using solvation parameter model. the system constants were determined by multiple linear regression analysis from experimental values in the retention factor for a group of different solutes with known descriptors by computer using the program spss/pc. the experimental results showed t...

Gold nanoparticles have a great number of applications, among others in material sciences, biology and medicine. A method for the synthesis of gold nanoparticles in solution with the use of gemini surfactant was proposed and the nanoparticles obtained were subjected to thorough characterisation. The method proposed is a modi cation of the Turkevich method, based on reduction of tetrachloroauric...

The design of nanoparticles desired sizes and shapes 2D nanostructured materials is challenging important due to their unique physical chemical properties. One the most common methods for generation metal wet synthetic route in which ions are reduced formed particles stabilized liquid phase. Here we show a facile powerful method synthesize gold solid agarose gel utilizing diffusion reagents usi...

With the spread of deadly diseases worldwide, design rapid tests to identify causative microorganisms is necessary. Due unique properties gold nanoparticles, these nanoparticles are used in designing diagnostic tests, such as strip tests. The current study aimed investigate ability bind single-chain variable fragment antibodies. In this study, biological and chemical methods included Escherichi...

The synthesis of gold nanoparticles using citrate reduction process has been revisited. A simplified room temperature approach to standard Turkevich synthesis is employed to obtain fairly monodisperse gold nanoparticles. The role of initial pH alongside the concentration ratio of reactants is explored for the size control of Au nanoparticles. The particle size distribution has been investigated...
