Cancer Phototherapy
The figure shows the effects of exposure of human tumor cells (HeLa) to the Photovoltaic Effect in volume (EFV). Both photographs show the same group of cells before (A) and after (B) of fototratamiento. In (A) shows the cells growing on the crystal of lithium niobate doped with iron before being exposed to visible light. In (B) shows the same cells that have suffered severe structural damage after illumination with visible light. Bubbles (rounded dark structures) on the cell surface indicates that the cells have undergone a process of death called necrosis. The arrows indicate the same cell in both images to facilitate location.
