The Developmental Toxicity of Complex Silica-Embedded Nickel Nanoparticles Is Determined by Their Physicochemical Properties - Fig 3

<p>A. % total SiO₂ dissolution from CENs dispersed in E3 medium for five days at room temperature with a starting concentration of 200 mg Ni/L. TEM images on day five of B. Ni-SiO₂, C. nhNi@SiO₂ and D. hNi@SiO₂. Scale bars are 200 nm for larger images (black) and 50 nm for smaller pictures (white). All three CENs exhibited minimal silica dissolution.
