“…If the mechanism of the CNT-seed interaction is through the facilitation of water uptake, then this is also expected to enhance mineral nutrient uptake and affect growth. However, given the fact that CNTs purportedly display a marked interaction with ions and polar molecules (Miskovic 2008;Frolov et al 2012), it would be interesting to see how enhanced water delivery versus ion-CNT interactions play out as far as seedling nutrient uptake is concerned. The mechanism of ionic interactions with the CNT surface (Miskovic 2008) implies that redox type changes of the nutrient ion of a given oxidation state might take place with the MWCNTs in the medium.…”

This is explored in the later part of this work with the introduction of the important mineral nutrient iron as Fe(II) and Fe(III) chloride in agarose gel.…”

The application of nano-biotechnology to cropscience/agriculture ('nanoagriculture') is a recent development. While carbon nanotubes (CNTs) have been shown to dramatically improve germination of some comestible plants, deficiencies in consistency of behavior and reproducibility arise, partially from the variability of the CNTs used. In this work, factory-synthesized multi-walled-CNTs (MWCNTs) of quality-controlled specifications were seen to enhance the germinative growth of maize seedlings at low concentrations but depress it at higher concentrations. Growth enhancement principally arose through improved water delivery by the MWCNT. Polarized EDXRF spectrometry showed that MWCNTs affect mineral nutrient supply to the seedling through the action of the mutually opposing forces of inflow with water and retention in the medium by the ion-CNT transient-dipole interaction. The effect varied with ion type and MWCNT concentration.
