Effects of drug dosage, oxygen level, and photoirradiation time on cell viabilities of TNBC cells, MDA-MB-231. a Cell viabilities of MDA-MB-231 treated with various concentrations of PpIX (0, 0.2, 0.4, 0.8 µM) under 21 % O2 for different photoirradiation times (0, 1, 2, 3, 4 min). b Cell viabilities of MDA-MB-231 treated with various concentrations of PpIX under 5 % O2 for different photoirradiation times. c Cell viabilities of MDA-MB-231 treated with various concentrations of PpIX under 2 % O2 for different photoirradiation times. d Cell viabilities of MDA-MB-231 treated with various concentrations of PpIX under 1 % O2 for different photoirradiation times. e Cell viabilities of MDA-MB-231 treated with various concentrations of TPZ (0, 20, 60, 100 µM) under different oxygen levels (21 %, 5 %, 2 %, 1 %). MTT assay was used to confirm cell survival after 24 h
