Изучалось стимулирующее действие малых доз графена (0,2 мг/л, 2 мг/л и 20 мг/л) на растения двух видов: кукурузы и огурца - в отношении которых ранее проводились исследования стимуляции более высокими дозами и угнетение еще более высокими дозами углеродных наноматериалов. Применяемый в нашем исследовании графен получен оригинальным суперкавитационным способом и охарактеризован стандартными методами: электронной микроскопией и методом комбинационного рассеяния света. Спектры комбинационного рассеяния света свидетельствовали о наличии нанопластин толщиной от 1 до 5 атомных слоев углерода. Максимальное стимулирующее действие графена проявилось при концентрации графена в водной суспензии 20 мг/л. При концентрации 0,2 мг/л стимулирующее действие не обнаружено.

A stimulating effect has been studied of low doses of graphene (0.2 mg/l, 2 mg/l and 20 mg/l) on two species - corn and cucumber plants. (Earlier, these species had already been studied regarding stimulation by higher doses, and suppression by even higher doses, of carbon nano-materials.) The graphene used was obtained by original supercavitation method and was characterized by electron microscopy and by the Raman scattering. The spectra of the Raman scattering indicated the presence of 1 to 5 carbon atomic layers thick nanoplates. In this investigation, the maximum stimulating effect of graphene was revealed at the graphene concentration of 20 mg/l in an aqueous suspension. At the concentration of 0.2 mg/l no stimulating effect has been detected.
