Metal nanoparticles are vast because of their exceptional physical and chemical properties resulting from characteristics such as quantum size effects and huge surfaces. Although all metal nanoparticles are unique in their own way, the most intriguing of all metals is the aurum (Au) or gold nanoparticle due to the chemical and physical versatility of its nanoparticles' surface. The usages of Au nanoparticles are already implemented into chemical separation, sensor, and medicine, for diagnosis of cancer. It is believed that organic conducting polymers exhibit electrical, electronic, magnetic, and optical properties of metal while acceding to the mechanical properties and process abilities of conventional polymers. Therefore, by reincorporating Au nanoparticles into conducting polymers, the: polymer/metal nanocomposites display superior sensing, catalytic capabilities, and conductivities in contrast to pure conducting polymers.
