水溶性碳纳米管（wsCNTs）对菊苣（Cicer arietinum）植物的生长有促进作用。当wsCNT浓度达到6.0 μ mL（-1）时，植株的根、芽、分枝等各部位的生长速率均有所提高。wsCNT处理和对照植株的显著差异是吸水量；在前者中，它显着增强，表明更好的吸水率和保水率与促进生长有关。这项工作表明，与碳纳米管不同，wsCNTs对植物细胞无毒，可以保存植物中的水分运输。
Water soluble carbon nanotubes (wsCNTs) show enhancement of the growth rate of common gram (Cicer arietinum) plants. Treating plants with up to 6.0 μg mL(-1) of wsCNT shows an increased growth rate in every part of the plant including the roots, shoots and also in branching. The noticeable difference between the wsCNT treated and controlled gram is the water uptake; in the former it is dramatically enhanced, suggesting better water absorption and retention related to enhanced growth. This work shows that unlike CNTs, wsCNTs are non-toxic to plant cells that conserve water transport in plants.
