| 内容記述 | Carbon nanotubes (CNTs) have attracted much business interest in industrial applications due to their high electrical and heat conductivities while being both durable and versatile. However, multiwall CNTs (MWCNTs) of ~50 nm diameter (NT50) have been shown to cause mesothelioma in rodents after direct exposure to mesothelial cells, and thus were classified as a Group 2B carcinogen to humans, which requires considerable regulations for use. In contrast, tangled MWCNTs of ~15 nm diameter (NTtngl) are not carcinogenic to rats, indicating that the physical dimension linked with mesothelial cellular uptake is an important factor for human environmental risk. In the present study, hypothesizing that dustability is another distinct risk factor, for the first time, we evaluated the toxicity of CNT granules (Durobeads) that were generated with a polymer coating to mesothelial cells. Polymer coating induced prominent agglomeration and significantly suppressed the dustability of CNTs in a dose-dependent manner, with a 10% polymer coating resulting in 730 times less dustability. These CNT granules revealed significantly lower mesothelial uptake and cytotoxicity in comparison to NT50 in in vitro assays. Similarly, in in vivo analyses, CNT granules induced limited peritoneal inflammation 4 weeks after intraperitoneal injection, whereas NT50 caused severe fibrosing inflammation. Previously, we demonstrated that the severity of inflammation by intraperitoneal injection in the subacute studies are in agreement with the mesothelial carcinogenicity by CNTs. Therefore, we suggest that adding a polymer coating to CNTs provides another smart strategy for the safe use of CNTs. | |||||
