In this study, two types of carbon nanotube (CNT) modified surfaces for the attachment of Bacillus anthracis spores were examined. Multi-walled carbon nanotube (MWCNT) forest on silicon wafer and MWCNT sheet on poly(methyl methacrylate) (PMMA) film were used. Both types of MWCNT surfaces significantly increased surface hydrophobicity (P < 0.05) and increased the attachment of spores on their surfaces compared to the uncoated substrates, respectively. However, no inhibitory effect was observed on the germination of attached spores on both types of MWCNT surfaces. MWCNT-coated surfaces showed the potential as adsorbents for removal of Bacillus spores from fluids.
在这项研究中，考察了两种用于附着炭疽芽孢杆菌孢子的碳纳米管 (CNT) 修饰表面。使用了硅片上的多壁碳纳米管 (MWCNT) 森林和聚甲基丙烯酸甲酯 (PMMA) 薄膜上的 MWCNT 片。与未涂层的基底相比，这两种类型的 MWCNT 表面都显著增加了表面疏水性 (P < 0.05)，并分别增加了孢子在其表面上的附着。然而，在这两种 MWCNT 表面上，附着的孢子的萌发都没有观察到抑制作用。MWCNT 涂层表面具有作为从流体中去除芽孢杆菌孢子的吸附剂的潜力。
