Abstract
Green synthesis of nanoparticles using plants has rapidly emerged as an environmentally friendly, cost-effective, and sustainable approach within the expanding field of nanotechnology. This comprehensive review aims to thoroughly explore the potential of plant-mediated synthesis as a viable alternative to traditional chemical and physical methods of nanoparticle production, which often rely on toxic chemicals, hazardous reagents, and energy-intensive processes. By utilizing plant extracts that are rich in bioactive compounds, such as alkaloids, terpenoids, flavonoids, and phenols, the synthesis process benefits from the natural reducing and stabilizing properties these compounds offer. These bioactive compounds play a crucial role in controlling the size, shape, and stability of the nanoparticles, allowing for precise and efficient nanoparticle formation. The review provides an in-depth examination of a wide range of plant species that have been explored for the synthesis of various metal nanoparticles, including gold, silver, platinum, copper, and other metals, and outlines the complex mechanisms involved in nanoparticle formation, such as reduction, nucleation, and growth processes. Furthermore, the review highlights the significant advantages of the green synthesis method, including enhanced biocompatibility, low toxicity, and environmental sustainability, making it an attractive alternative to conventional synthetic techniques. Despite these advantages, the review also addresses several challenges and limitations associated with scaling up the process for industrial applications, such as standardization, consistency, and cost-effectiveness. In addition, the review investigates the promising potential applications of plant-derived nanoparticles in a range of fields, including biomedicine, environmental restoration, agriculture, and energy. These applications illustrate the transformative potential of plant-mediated nanoparticle synthesis in addressing global sustainability challenges, underscoring the role of green nanotechnology in advancing eco-friendly and sustainable solutions for the future. Ultimately, the review emphasizes the growing importance of plant-based approaches in the development of next-generation nanoparticles and their potential to drive the future of sustainable nanotechnology.
