研究了多壁碳纳米管团聚体对植物细胞的毒性。以拟南芥T87悬浮细胞为模型细胞，在含有多壁碳纳米管团聚体的培养基中培养的细胞干重、细胞活力、叶绿素含量和超氧化物歧化酶（SOD）活性均降低，表明多壁碳纳米管团聚体对拟南芥T87悬浮细胞具有毒性。而且。随着多壁碳纳米管团聚体直径的减小，毒性急剧增加。基于过敏反应的概念，建议解释可能的毒性机制的多壁碳纳米管诱导。(C)2009 Elsevier B.V.保留所有权利。
The possible toxicities of agglomerates of multi-walled carbon nanotubes (MWCNTs) toward plant cells were evaluated. Arabidopsis T87 suspension cells were used as the model cells and decreases in values of cell dry weights, cell viabilities, cell chlorophyll contents, and superoxide dismutase (SOD) activities were seen for the cells cultured in media containing the agglomerates of MWCNTs, indicating the agglomerates of MWCNTs are toxic to the Arabidopsis T87 suspension cells. Moreover. the toxicities increased sharply as the diameters of the agglomerates of the MWCNTs became smaller. A concept based on the hypersensitive response is suggested to explain the possible toxic mechanism induced by the MWCNTs. (C) 2009 Elsevier B.V. All rights reserved.
