Effects of kelp-derived carbon dots on embryonic development of zebrafish

Common algae kelp in aquaculture was utilized as a raw material and synthesized biomass carbon dots through a green, convenient, and efficient hydrothermal method. This approach ensures environmentally friendly and pollution-free production from raw material selection to material synthesis. Zebrafish model organisms were selected as research objects to explore the fluorescence imaging and metabolism of different concentrations of carbon dots during the development of zebrafish embryos. Furthermore, the effect of carbon dots on zebrafish embryo development including hatching rate, heart rate, and survival rate of adult fish were studied to evaluate kelp-derived carbon dots' biosafety.
