Effect of PET NPs on hatching ( |
Representative images showing the effect of PET NPs on early stages of zebrafish embryo development. Embryos (6 hpf) were treated with different concentrations of PET NPs (0, 10, 50 and 100 ppm) for 24 h ( |
Representative Fluorescent confocal images (successive slices) showing the distribution of PET-NR nanoparticles in the body of zebrafish embryos (96 hpf) that were exposed to 100 ppm PET-NR nanoparticles for 24 h as compared to embryos treated with only NR (control). As can be noticed, nanoparticles are accumulated at various locations including intestine (a), pronephric duct/kidney (b), liver (c) and brain. Images were acquired using inverted laser-scanning confocal microscope (Leica DMi8 / TL LED, Leica Microsystems CMS GmbH). Scale bar: 1 mm. |

Effect of PET NPs treatment on the metabolic profile of intact zebrafish embryos. Zebrafish embryos (72 hpf) were exposed to 100 ppm PET NPs for 24 h. Concentrations of metabolites relative to total creatine (tCr) are shown. For statistical analysis, one-way ANOVA with a Tukey post-hoc correction for multiple comparisons were performed using OriginPro v. 8 (Northampton, MA, USA). Values shown are the mean ± standard deviation (n = 6). The statistically significant differences in metabolites between PET NPs treated and control group obtained by ANOVA analysis are indicated by # |
