Evaluation of ‘green’ synthesis and biological activity of gold nanoparticles using Tragopogon dubius leaf extract as an antibacterial agent

Abstract: Currently, the use of 'green' synthesised nanoparticles with environmentally friendly properties is considered a novel therapeutic approach in medicine. Here, the authors evaluated gold nanoparticles (AuNPs) conjugated with Tragopogon dubius leaf extract and their antibacterial activity in vitro and in vivo. Colour changes from yellow to dark brown and a peak at 560 nm on ultraviolet-visible spectroscopy confirmed the formation of nanoparticles. Additionally, transmission electron microscopy, Xray diffraction,… Show more

“…The plant extracts synthesized gold nanoparticles (AuNPS) have been investigated by multiple studies for their antibacterial activity against S. aureus. Mangifera indica seed extract (Vimalraj et al, 2018), Callistemon citrinus seed extract (Rotimi et al, 2019), Justicia glauca leaf extract (Emmanuel et al, 2017), Camellia japonica leaf extract (Sharma et al, 2019), Alternanthera bettzickiana leaf extract (Nagalingam et al, 2018), Tragopogon dubius leaf extract (Layeghi-Ghalehsoukhteh et al, 2018) Origanum vulgare leaf extract (Benedec et al, 2018), Ocimum tenuiflorum flower extract (Rao et al, 2017), Nigella arvensis leaf extract (Chahardoli et al, 2018), and Elettaria cardamomum seed extract (Rajan et al, 2017) are some examples of the plant extracts that were recently utilized for the fabrication of AuNPs with antibacterial ability against S. aureus. Further, there are some studies that took advantages of mixture of extracts from two different plants for the synthesis of AuNPs with potential against S. aureus.…”
