Characterization and toxicity of selenium nanoparticles (SeNPs). (a) Scanning electron micrograph of SeNPs. (b) Raman spectrum of SeNPs. Peaks at 234 and 251 cm-1 are consistent with elemental selenium in a six-membered ring structure.49 (c) Dose-response relationships for SeNPs, SeNPs + CdCl2. The LC50 value for SeNP + CdCl2 was 27 (CI95%: 17-40) μM Cd equivalents. In some cases, error bars are smaller than the size of the symbols. (d) Images of zebrafish larvae at 120 hpf exposed to SeNPs in the presence or absence of CdCl2.
