The interaction of meso-tetrakis(4-N-methyl-pyridiniumyl) porphyrin (TMPyP) with DNA has been investigated at ionic strength (IS) values of 0.01 and 0.20 M (pH 6.8) using the flash-photolysis technique along with optical absorption and fluorescence data. It is found that the aggregation of TMPyP obs
