The article discusses the synthesis of metal nanoparticles using plant extracts as an environmentally friendly and cost-effective alternative to traditional chemical and physical methods. It highlights the role of plant biomolecules in the bioreduction of metal ions, leading to the formation of nanoparticles with specific properties. The review covers various factors influencing nanoparticle morphology, size, and yield, including the types of plant metabolites involved, such as terpenoids, flavonoids, sugars, and amino acids. The study also examines the effects of pH, temperature, and electrochemical potential on nanoparticle formation. The use of plant extracts in combination with exogenous biomatrices like peptides and proteins is explored, demonstrating their effectiveness in producing nanoparticles with controlled size and shape. The article emphasizes the potential applications of plant-derived nanoparticles in various fields, including medicine, environmental remediation, and catalysis. It also discusses the advantages of "green" synthesis, such as reduced environmental impact and the use of plant waste as reducing agents. The review concludes that while plant-based nanoparticle synthesis has significant potential, further research is needed to optimize the process and ensure its scalability for practical applications.The article discusses the synthesis of metal nanoparticles using plant extracts as an environmentally friendly and cost-effective alternative to traditional chemical and physical methods.
