在自然界中，季节变换带来了树叶色彩的丰富变化，尤其是秋天的树叶变色现象，吸引了无数目光和科学探索。但在这背后，是一系列复杂的化学变化和色素分子结构的巧妙调整。本文将深入探讨秋天树叶变色的化学结构基础。

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.
