Impacts of surface chemistry of functional carbon nanodots on the plant growth.

摘要: Functional carbon nanodots (FCNs) with multiple chemical groups have great impact on the growth regulation of plants. To understand role groups, FCNs were reduced from raw material by pyrolysis method and hydrolysis method. The structure these materials characterized using TGA, TEM, FT-IR, XPS, Raman elementary analysis. used as plants regulators in culture medium Arabidopsis thaliana. Our results indicate there is a strong correlation between physiological responses surface chemistries (especially carboxyl group ester group) nanomaterials. quantum-sized show better aqueous dispersity can induce various positive thaliana seedlings compared decorated without well aggregated FCNs. present higher promotion capacity biomass roots length, are easier to be absorbed generate more effects
