Characterizations of QDs and screening their impacts on the eye development of zebrafish. a) Representative images of QDs by TEM, scale bar, 50 nm. b) The Raman intensity of QDs. c) The lateral views of the effect of QDs (1 mg L⁻¹) on retinal development in Tg (Atoh7:gapRFP::Ptf1a:GFP::Crx:CFPcaax) zebrafish at 168 hpf. The retinal ganglion cell layer (GCL) is labeled by red fluorescence protein (RPF), the inner nuclear layer (INL, including AC and HC) is labeled by green fluorescent protein (GFP), and cyan fluorescent protein (CFP), BC is labeled by CFP, and outer nuclear layer (ONL, composed of PR) labeled by RFP and CFP. Scale bar, 100 µm.
