The PDT damaging on KB cells, measured by a MTT assay. Except the control groups, cells were incubated with free AlPcSs (5 μM), QDs (0.05 μM) or AlPcS-QDs (0.05 μM) for 50 min, respectively, followed by the irradiation of a 532-nm laser (a) or a halogen lamp (b). In AlPcS' column in Figure 4b, cells had been incubated with AlPcSs (5 μM) for 3 h and were then irradiated.
