“…The results of FTIR-ATR studies showed that the functional groups of the diverse metabolites react with the Au 3+ ions and regulate the size of AuNPs in the nanoscale range. Earlier, the role of polyphenol compounds in the formation and stabilization of metal NPs has been discussed in several reports (Mariychuk et al 2019;Wacławek et al 2018). The common idea is that the hydroxyl groups (OH) of the polyphenol compounds are partially oxidized to polyketones and polyaldehydes that are, subsequently, the AuNPs' stabilizers.…”

In the present article, we reported the application of the extract of leaves from Solidago canadensis L. for the green synthesis of triangular and hexagonal gold nanoparticles (AuNPs). The phytochemical characterization, by reaction with HAuCl 4 solutions, showed that the extract of Solidago canadensis L. contained the secondary metabolites that can act both as reducing and as stabilizing agents. For the synthesis of AuNPs, the effects of the HAuCl 4 concentration (0.25-0.975 mM) and the reaction time (10-180 min) were investigated. The formation of AuNPs is confirmed by the color change from yellowish to purple-red. Photoluminescence measurements of Au nanocolloids showed a continuous emission band ranging from violet to red. UV-Vis characterization of AuNPs in the prepared nanocolloids showed surface plasmon resonance peaks at 530 and > 870 nm. TEM revealed that the AuNPs are in the range of 8-200 nm, they have spherical, triangular, and hexagonal forms of varying sizes. AFM and STM showed a non-ideal relief of large triangular and hexagonal gold nanoprisms. The EDX analysis, XRD and SAED patterns confirmed the face-center cubic structure of AuNPs.

Gymnosperms, also termed as Acrogymnospermae, are an assemblage of seedbearing vascular plants that contain "naked" seeds. Although the early evolutionary history of seed plants is a bit tricky and confusing due to inconclusive fossil evidences, recent molecular phylogenetic studies place extant gymnosperms in a monophyletic group allied to the Magnoliophyta. All major groups of gymnosperms have found usage in the nanofabrication nanoparticles with majority of the studies carried out in the last 10 years. Among the gymnosperms, conifers have been the popular choice in the eco-friendly synthesis of nanoparticles primarily due to the structural and chemical diversity of natural compounds present in different members of this group. Ginkgo, Cycas, and Ephedra have also yielded nanoparticles, while Gnetum has also been utilized to some extent.
