The project involved synthesizing two hybrid organometallic nanocomposites, including gold nanostar using tween 80 and nanocomposites based on silver nanoparticles from polysaccharides, lactose/alginate. Both nanocomposites were applied for chemical sensors and catalysis. The properties of these nanocomposites were characterized by modern analytical techniques. The gold nanostars were employed for the quantification of iodide and iodobenzene using colorimetric sensing using UV-Vis spectra. Meanwhile, silver nanoparticles on polysaccharides were utilized for sensing Fe3+ ions and proved to be an effective catalyst for organic dye reactions.
The project contributed to the training of the research team, especially young researchers at the Institute of Chemical Technology in the field of material science. Additionally, the study successfully trained one master's degree holder, a young researcher at the Institute of Chemical Technology. The project also facilitated the exchange of two members between two research teams, enhancing collaboration between the two research institutes. Furthermore, the international cooperation task also supported the research team in developing new research directions.

The project has developed a novel method for synthesis of gold nanostars using Tween 80 as a surface-active agent, in the presence of the weak reducing agent as hydroquinone. The gold nanostars was employed for developing an optical sensor to quantify iodide ions and iodobenzene. Additionally, a water-dispersible nanocomposite from silver nanoparticles loading on polysaccharides was investigated and developed for applications in catalysis and sensing of Fe3+ ions.

Although the objectives have been achieved, within the two-year timeframe of the project, the research team has not been able to complete in-depth studies on the synthesized nanocomposite materials, such as the reaction mechanisms of gold nanostars and organic iodine. Therefore, the research team suggests seeking further support to continue developing research collaborations with partners in the future.
