The folate-fluorescein combination binds to the surface of the tumor cell. Then the immune system recognizes fluorescein as a foreign invader and sends antibodies to attack it.

Infection-fighting blood cells act as a kill and cleanup crew, attacking the fluorescein, killing the cancer cell, and then eating it up.

If the Food and Drug Administration allows the animal study results to proceed to human clinical trials, medical science may have found a discovery for which cancer researchers and patients have long been waiting.
