Using gold nanoparticles as a carrier for iodine opens possibilities of new treatments for cancer and also for tracking cancerous cells. To design an optimized version of gold nanoparticle for such purpose, we need to understand the bonding mechanism and gauge the strength of such bonding. To this end we performed theoretical calculations on the adsorption state of iodine on gold (111) surface. The results show good adsorption of iodine to gold, most stably on the hollow sites. The bonding mechanism is via the hybridization of the 5p orbital of the iodine with the 6s and 5d orbitals of the neighboring gold atoms. These results act as a first step to designing an optimized gold nanoparticle that can be used in future radiotherapy treatments.
