“…Consequently the analytical sensitivity markedly improves, permitting trace level analysis. We have shown (Alvarado et al 2013 in press) that samples of masses lower than the recommended mass for ideal analysis (as frequently occur in the biosciences), can be analyzed for relative elemental concentrations with sufficient accuracy. The detectable elemental range is from Na to U.…”

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.

“…[21] Techniques for heavy metal quantitative and qualitative analysis vary in the amount of sample preparation required from bulk to surface measurements. [22,23] For bulk and quantitative measurement of metals which require separation of plant parts, drying, and acid digestion [1,9,19] ; atomic absorption spectroscopy [24][25][26][27][28][29] allows single element analysis at low concentrations, [22,30] while the inductively coupled plasma (ICP) [1,6,9,19,[31][32][33] allows analysis of up to 70 elements at low concentrations. [22,30] In general, acid digestion and considerable sample treatment are the disadvantages of these methods.…”

The goal of this research was to visualize the uptake of copper by plants to promote phytoremediation. The hypothesis was that regions of the plant that contain more copper have enhanced nuclear magnetic resonance using copper as a paramagnetic contrast agent. Earth field magnetic resonance imaging (EFMRI) spectrometry uses a magnetic field 300,000 times weaker than a 600 MHz nuclear magnetic resonance spectrometer. As in conventional human MRI, this portable instrument is capable of recording one, two, and three dimensional images, although the sample size is reduced. The enhancement of signal was first demonstrated recording the two dimensional images of different concentrations of aqueous copper sulfate. The study also focused on growing mesquite and soybean plants in hydroponic media containing 0.25 mM copper nitrate for four and three weeks, respectively, and recording their EFMRI images with plants grown without copper nitrate. The results showed that EFMRI allows the probing the plant absorption of copper without having to dissect the specimen and therefore requires less sample preparation and time than current techniques. This technique may be beneficial to phytoremediation by imaging plants to evaluate their copper accumulation.
