Representative SEM images obtained for (a, b) reference A375 cell line, and A375 cells treated with multilayered 2D sheets of Ti₂NT_x MXene at a concentration of (c–e) 62.5 mg L⁻¹ and (f–h) 500 mg L⁻¹. SEM analysis was performed with SE mode (a–g) as well as AsB (d, h). 2D Ti₂N sheets internalized by A375 cells were marked with red arrows, whereas those only attached to the cells’ surface were marked with white arrows
