Assimilation of Multiwall Carbon Nanopipes to Developing Plants

The concentration of carbon nanopipes (CNPs) can be detected and quantitatively measured in various matrices, including biological ones, using the methodology of formation of a gamma-emitting radioactive isotope marker in a CNP. The methodology has been tested in a 10-day experiment on the sprouting of wheat seeds on an artificial substrate damped by a water suspension of radioactively marked Taunit-M multiwall CNPs (MCNP) (Russia). Changes in the activities of samples of developing plant organs—root system, coleoptile and root base, and stem with leaves—makes it possible to define the quantitative concentration of MCNPs passing from a substrate with a known concentration of the given nanomaterial into a plant. The results show promising outlooks for applying this methodology for quantitative measurements of CNP mass/concentration in various media and biological objects.
