Functional silver-based nanomaterials affecting zebrafish development: the adverse outcomes in relation to the nanoparticle physical and chemical structure

Summary

Researchers investigated how silver-based nanoparticles with different physical and chemical properties affect zebrafish embryo development. They found that nanoparticles coated with the polymer hydroxyethyl cellulose, combined with small particle size and a positive surface charge, showed increased biological reactivity toward the embryos. The study highlights how the design and surface chemistry of nanomaterials can significantly influence their toxicity to aquatic organisms.
