The present study was conducted to assess the toxicity of nanosized silver particles (Ag-15nm, 30nm and 55nm) in rat alveolar macrophages. For toxicity evaluations, cellular morphology, mitochondrial function (MTT assay), membrane leakage (LDH assay) and reactive oxygen species generation (ROS) were assessed after a 24h under control and exposed conditions. The morphological appearance of control and exposed cells were observed by an inverted, phase contrast microscope and the uptake of nanoparticles was observed using the CytoViva Ultra Resolution Imaging (URI) system. Morphological images captured at 100x magnification demonstrated that nanoparticle-exposed cells at higher doses became abnormal in size, and most …
