For more than 60 years, researchers have tried to successfully cryopreserve (or freeze) the embryo of zebrafish, a species that is an important medical model for human health. In a new study, researchers at the University of Minnesota and the Smithsonian Conservation Biology Institute (SCBI) provide the first-ever reproducible evidence for the successful cryopreservation of zebrafish embryos.

The study uses new gold nanotechnology and lasers to warm the embryo—the stumbling block in previous studies. The results have profound implications for human health, wildlife conservation, and aquaculture.
