Gold nanoparticles (Au NPs) have been extensively investigated as contrast and dose enhancing agents. Bismuth sulfide (Bi2S3)-NPs have recently been investigated as contrast agents in radiology. In this study the dose enhancing effects of Bi2S3-NPs on radiated mouse PC3 prostate and B16 melanoma cells were examined. Equimolar concentrations of both Au and Bi2S3-NPs displayed equal dose enhancement with B16 cells, while the latter provided higher values with PC3 cells.
