Active targeting performance analysis of Ti₃C₂/Apt-M nanosheets. Flow cytometry analysis of a MCF-7 and b HepG2 cells after incubation with Apt-Cf or Apt-Mf. Flow cytometric analysis of (c) MCF-7 and (d) HepG2 cells incubated with Ti₃C₂/Apt-Mf nanosheets for different time (0, 1, 2, 3, 4, 5 and 6 h). Flow cytometric analysis of e MCF-7 and f HepG2 cells incubated with Ti₃C₂/Apt-Mf, Ti₃C₂/Apt-Mf with free Apt-C, Ti₃C₂/Apt-Mf with free Apt-M for 4 h. g CLSM images of MCF-7 and HepG2 cells incubated with Ti₃C₂/Apt-Mf for 2, 4 and 6 h.
