Nanoscale zero-valent iron (nZVI) is a "redox"-active nanomaterial used in the remediation of contaminated groundwater. To assess the effect of "aging" and surface modification on its potential neurotoxicity, cultured rodent microglia (BV2) and neurons (N27) were exposed to fresh nZVI, "aged" (>11 months) nZVI, magnetite, and polyaspartate surface-modified (SM) nZVI. Increases in various measures of oxidative stress indicated that BV2 microglia responded to these materials in the following rank… CONTINUE READING
