ABSTRACT: Objective
Silica nanoparticles (SiO2 NPs) have been extensively employed in biomedical field. SiO2 NPs are primarily designed to enter the circulatory system; however, little information is available on potential adverse effects of SiO2 NPs on the nervous system.Methods
The neurotoxicity of SiO2 NPs at different concentrations (3, 6, 12 ng/nL) on zebrafish embryos was determined using immunofluorescence and microarray techniques, and subsequently confirmed by qRT-PCR.Results
SiO2 NPs disrupt the axonal integrity and decrease the length of axons in Tg (NBT: EGFP) transgenic lines. The number of apoptotic cells in the brain and central nervous system of zebrafish embryos was increased in the presence of 12 ng/nL o
