Cellular uptake and nuclear localization of Ti-TCPP MOF in BxPC-3 cells. Flow cytometry (a), ICP analysis (b) and confocal images (c) of BxPC-3 cells after incubation with Ti-TCPP MOF at different time periods. Scale bar: 20 μm. (n = 3). (d) Bio-TEM images of BxPC-3 cells before and 6 h after incubation with Ti-TCPP MOF. Scale bar: 2 µm. Red arrows denote Ti-TCPP MOF. *P < 0.05, ***P < 0.001
