| Abstract: | Metallic nanoparticles can be synthesised in living plants, which provide a friendly approach. In this work, the authors aimed to study the synthesis of silver nanoparticles (AgNPs) in Arabidopsis and the two‐dimensional (2D) distribution of Ag and other elements (Ca, P, S, Mg, and CI) in the Arabidopsis plant tissues. The concentrations of Ag in the plant tissues were determined by inductively coupled plasma‐atomic emission spectrometer, showing that the majority of Ag was retained in the roots. Transmission electron micrographs showed the morphology of AgNPs and the location in plant cells. The distributions of Cl and Ag were consistent in plant tissues by 2D proton‐induced X‐ray emission. In conclusion, this is the first report of the AgNP synthesis in Arabidopsis living plants and its 2D distribution of important elements, which provide a new clue for further research.Inspec keywords: silver, botany, atomic emission spectroscopy, antibacterial activity, nanoparticles, nanofabrication, transmission electron microscopy, chlorine, calcium, sulphur, phosphorusOther keywords: biosynthesis, two‐dimensional element distribution, metallic nanoparticles, silver nanoparticles, Arabidopsis plant tissues, inductively coupled plasma‐atomic emission spectrometry, transmission electron micrography, plant cells, 2D proton‐induced X‐ray emission, Arabidopsis living plants, Ag, Cl, Ca, P, S, Mg |
