A microfluorimetric investigation of the dynamics accumulation of a porphyrin type photosensitizer in normal and malignant cells

Intercellular fluorescence of a photosensitizer-dye (hematoporphyrin) with its bonding with normal and malignant cells is investigated. The spatial distribution of the dye in a cell and the dependence of the intensity of the fluorescence of cells of the culture on curing time in the dye are studied, along with the effect of change in the acidity of the medium on the penetration of the porphyrin into the cell.
