    • 4 in 5 mL water) were added to the reaction mixture and stirring was continued for 5 min. Formation of gold nanoparticles was indicated by the color change. This solution was stored and used in reactions. OCP hydrolysis in the presence of gold nanoparticles. This reaction was carried out in the presence of AP-1 sodium salt at three different concentrations (0.001, 0.1 or 1 mg/mL), in the presence of gold nanoparticle solution (1.8 mg/L) at pH 7.4, by maintaining the temperature at 70°C for 48 h. A pink colored product appeared in the case of added gold particle solution, which was filtered and repeatedly washed with double distilled water and dried at 37°C. Morphology of the product so obtained was studied by powder X-ray diffraction and other microscopic techniques.

    • Scanning electron microscopy and EDAX analysis. Samples were gold sputter-coated prior to imaging and the scanning was carried out with FEI QUANTA 200 scanning microscope to observe size and morphology of the samples. However, energy dispersive X-ray was taken using copper stubs as the composite contained colloidal gold.
