Abstract
Nowadays, gold nanoscience and nanotechnology are receiving significant attention owing to their unique material properties and an increasing range of applications. The distinctive characteristics of gold nanoparticles (AuNPs), such as non-toxicity, biocompatibility, and inertness, along with unique physical and chemical properties, make them ideal for numerous implementations across scientific research and multiple industries. Additionally, the continuously rising demand for AuNPs and the increasing global market share have spurred researchers to develop techniques for large-scale production. This review summarizes the different AuNPs production methods and achievements provided by various approaches through scientific publications. Although physical and chemical methods are predominant in the AuNP production industry, specific attention is being paid to biological AuNP fabrication due to there has been increasing focus on creating eco-friendly and green processes for gold nanoparticle production. Specifically, the use of living plants for AuNP synthesis has emerged as an environmentally friendly approach, offering promising solutions for sustainable AuNP production. This review highlights the significance of this plant-mediated synthesis and explores its potential as a viable method for AuNP fabrication, paving the way for further innovations in green nanotechnology.
