The photodynamic reaction in combination with electroporation performed on a LoVo and b LoVoDX cell lines. After electroporation with parameters: 1,250 V/cm, 50 μs, five impulses; cells were incubated with porphyrins during 20 min then irradiated with two wavelengths (435 and 530 nm) then 24 h of incubation without the compound followed. Each bar represents the mean of at least four separate experiments; bars are the standard errors, *p ≤ 0.05
