Zebrafish (Danio rerio) are widely used as a model organism for developmental biology. But after being frozen and thawed, zebrafish embryos rarely survive, meaning that researchers can only do experiments on live ones and can’t store embryos for later experiments or to share with other labs.

Now, researchers report that injecting zebrafish embryos with gold nanorods can improve their viability when thawed, offering the possibility of long-term storage. With further development, the technique could also . . .
