Nuclei Overlap (1 of 3)

Caption

Iridium with its organic coat which is hooked up to the protein albumin (HSA). Together that enter cancer cells and deliver the iridium photosensitizer to the nucleus. On irradiation with blue light, the iridium not only glows green, but converts oxygen in the cell to a toxic form called triplet oxygen, which kills the cell.
