Abstract A classification‐based cytotoxicity nanostructure–activity relationship (nanoSAR) is presented based on a set of nine metal oxide nanoparticles to which transformed bronchial epithelial cells (BEAS‐2B) were exposed over range concentrations (0.375–200 mg L −1 ) and exposure times up 24 h. The nanoSAR developed using data from high‐throughput screening assay that was processed identify label toxic (in terms the propidium iodide uptake BEAS‐2B cells) versus nontoxic events relative an...

A constant-number direct simulation Monte Carlo (DSMC) model was developed for the analysis of nanoparticle (NP) agglomeration in aqueous suspensions. The modeling approach, based on "particles a box" method, considered both particle and gravitational settling. Particle–particle probability determined classical Derjaguin–Landau–Verwey–Overbeek (DLVO) theory considerations collision frequency as impacted by Brownian motion. Model predictions were reasonable agreement with respect to size...

Nanomaterial structure–activity relationships (nano-SARs) for metal oxide nanoparticles (NPs) toxicity were investigated using metrics based on dose–response analysis and consensus self-organizing map clustering. The NP cellular dataset included profiles consisting of seven different assays human bronchial epithelial (BEAS-2B) murine myeloid (RAW 264.7) cells, over a concentration range 0.39–100 mg L−1 exposure time up to 24 h, twenty-four NPs. Various nano-SAR building models evaluated, an...

Most in vitro toxicity studies on engineered nanomaterials (ENMs) use transformed rather than primary cells for logistical reasons. However, may provide a more appropriate connection to vivo because these maintain their phenotypic fidelity and are also capable of differentiating into lineages that be differently affected by potentially hazardous ENMs. Few date have focused the role cellular differentiation determining ENM toxicity. We compared response undifferentiated differentiated human...
