Pseudocolored images of SMMC 7721 cells treated with 50 μg mL–1 PS-CDs at different voltage (a), gain (b), and concentration of PS-CDs (c), λex = 476 nm, λem = 485–525 nm (channel 1). Scale bar: 10 μm. In situ emission spectrum of LDs at a different voltage (d), gain (e), and concentration of PS-CDs (f). Scale bar: 10 μm
