Phytotoxicity assessment study of gold nanocluster on broad bean (<i>Vicia Faba L</i>.) seedling

In this study, we investigated the phytotoxicity of gold nanoclusters (AuNCs) on seed germination capacity, physiological response to stress and uptake, transport nanomaterials in broad beans. Although similar findings were observed for AuNCs bean root tip cells between micronucleus assays traditional experiments, former was more sensitive rapid. At experimental concentrations 0–200 mg/L, toxicity performance seedlings showed an overall positive correlation with concentration AuNCs. posed a potential risk environment at 20 mg/L. Moreover, studies uptake that smaller particles entering bean, higher coefficient, while materials not mainly adsorbed surface by competition potassium ions.
