In this study, we have prepared gold nanoparticles by chemical reduction method employing L-Tryptophane as a reducing agent for ionic gold. Approach: The gold nanoparticles are the most employed amongst the different metallic nanoparticles in the fields of nanomedicine and nanobiotechnology. Therefore, the employed method should provide suitable particle size, shape and particle distribution in order to obtain nanoparticles of high activity and efficiency indicating the importance of the technique. In this study, HAuCl 4 .3H 2 O, L-Tryptophane and polyethyleneglycol (PEG) were used to produce AuCl - 4 ions. They were acted as pre-material, reducing and stabilizing agents respectively. Results: The size, distribution and formation of gold nanoparticles were confirmed by Transmission Electron Microscopy (TEM) indicating the diameter of gold nanoparticles at the range of 10-25 nm and UV spectroscopy. The formed nanoparticles showed the highest absorption at 518 nm. Conclusion: The gold nanoparticles were stable in PEG1000. Since these nanoparticles have suitable size distribution they can be considered as a suitable candidate to be employed in nanomedicine and nanobiotechnology.

Consequently, the product becomes Shari’ah compliant but the core attributes of Islamic Economic System i.e. Justice and Social Welfare etc. are overlooked by the Industry. In other words, the conventional thinking of banking has an existence in Islamic Banking and only profit maximization concept is being considered rather than the concept of profit maximization with social welfare. This paper discusses all of such concerns and highlights the flaws and issues in the prevalent Islamic banking system and proposes suggestion/solution in this regard. The current depression i...
