Realizing comparable oxidative and cytotoxic potential of single- and multiwalled carbon nanotubes through annealing.

摘要: The potential applications as well the environmental and human health implications of carbon nanomaterials are represented in literature. There has been a recent focus on how specific physicochemical properties influence nanotube (CNT) function cytotoxicity. ultimate goal is better understanding causal relationship between fundamental physiochemical cytotoxic mechanism order to both advance functional design minimize unintended consequences CNTs. This study provides characterization data series multiwalled nanotubes (MWNTs) that underwent acid treatment followed by annealing at increasing temperatures, ranging from 400 900 °C. These results show MWNTs can be imparted with same toxicity single-walled (SWNTs) annealing. Further, we were able correlate this chemical reactivity MWNT suggesting it rather than physical hazard.
