The present invention provides for methods of treating a cancer patient. In one methods, cancer cells are harvested from a patient. A therapeutic amount of a rhodamine derivative is then added to the harvested cancer cells. The harvested cells and the rhodamine derivative are then irradiated with a suitable wavelength and intensity for the selective killing of the cancer cells. The irradiated cancer cells are then mixed with antigen presenting cells to form a mixture. The mixture of cancer and antigen presenting cells are then injected into the patient. The present invention also provides for methods of inhibiting or treating an immunological disorder, infection, or a cancer in an individual.
