Mortality of Drosophila embryos after microtransfer of nanomaterials at predicted environmental concentrations.

Notes: The effects of the nanomaterials were compared with the effects caused by microtransferring the liquid in which these were diluted. Treatments with IO nanoparticles are compared with treatment with H₂O (grey background), and Ag, Au, TiO₂, SWCNT, and MWCNT are compared with BSA 10% (white background). For each condition tested, n=50. *Statistical relevance was established through Fisher’s exact test (P<0.005).

Abbreviations: BSA, bovine serum albumin; IO, iron oxide; SWCNT, single-wall carbon nanotube; MWCNT, multiwall carbon nanotube; Ag, silver; Au, gold; TiO₂, titanium dioxide; H₂O, water; Cop, coprecipitation; Thermo, thermal decomposition.
