Zusammenfassung:Nanoscale materials known as nanoparticles exhibit distinctive properties and functionalities owing to their minute size and expansive surface area. Employing plant extracts for nanoparticle synthesis represents an environmentally conscious and sustainable method that utilizes natural resources as both reducing and capping agents. This comprehensive review presents the current state-of-the-art in the green synthesis of nanoparticles using plant extracts. It specifically explores the interplay between phytochemicals and metal ions, highlighting the impact of phytochemicals on various nanoparticle properties such as size, shape, morphology, crystal structure, elemental composition, surface charge, and optical characteristics. The applications of these nanoparticles such as silver nanoparticles, gold nanoparticles, zinc oxide nanoparticles etc. span diverse fields, including biomedical, environmental, catalytic, optical, electrical, and magnetic applications. The review also addresses challenges and future directions in this burgeoning field, emphasizing the necessity for standardization and optimization of synthesis parameters, elucidation of the synthesis mechanism and kinetics, and exploration of functionalization and potential applications. In conclusion, the green synthesis of nanoparticles using plant extracts emerges as a promising and evolving field with considerable potential for future research and development.
