suspension. Moreover, use of organic solvents and other
toxic chemicals may yield highly toxic products that hinder
bio-applications. The nanoparticles employed in this study
were highly stable and water soluble. The extent of toxicity
was measured in terms of mortality, hatching, heart rate
and abnormal phenotypes. Transmission electron microscopy
(TEM) of the Ag-BSA treated embryos showed a significant
concentration of nanoparticles inside the nucleus.
