Abstract
Giardia lamblia cell populations show 90% detachment from glass under normal forces of 2.43+/-0.33 nN applied by centrifugation. Detachment forces were not significantly different for cells attached to positively charged, hydrophobic, or inert surfaces than for cells attached to plain glass. The insensitivity of attachment force to surface treatment is consistent with a suction-based mechanism of attachment.
摘要
在通过离心施加2.43±0.33 nN的正常力作用下，蓝氏贾第鞭毛虫细胞群体显示出90%从玻璃表面脱离。与附着在普通玻璃上的细胞相比，附着在带正电荷、疏水或惰性表面上的细胞的脱离力没有显著差异。附着力对表面处理的不敏感性与基于吸力的附着机制一致。
