Fluoresence imaging, including bright-fifi eld (BF) images, showing the subcellular localization of the pN-CNDs with acid organelles (A–J) and mitochondria (K–T). The pN-CNDs were incubated with U251 cells for 1 and 2 h in each case. Green, red, and blue indicate the presense of LysoTracker,MitoTracker, and the pN-CNDs, respectively. Scale bars = 25 µm.
