FITC-SiO2-COOH NPs as a labeling agent in the Medaka fish model. (a) The FITC signal in the small intestinal tubes of 7 dpf larvae. (b) The FITC signal in the small intestinal tubes of 11 dpf larvae. (c) Mean gray value of the FITC signal in the larvae 0, 4, 24, and 48 h after NP exposure through a 4-h feeding window. (d) The FITC signal in the intestinal tubes of a newly hatched live brine shrimp. (e) The FITC signal in the intestine of the 11-dpf fish group, which ingested the NP-ingested brine shrimp. (f) The morphology of the 11-dpf fishes in control and NPs treated groups.
