Confocal microscopic visualization of Human embryonal kidney cell line 293T cells treated with PAA-capped green-emitting CdSe/CdS QDs (λ em max = 559 nm, about 3 nm in size) with the concentration of 5 μg/mL for 4 h at 37°C. From left to right, the panels show the transmission image, luminescence image, and an overlay of the two.
