ADVANCES IN THE GREEN SYNTHESIS OF PLANT-BASED NANOPARTICLES AND THEIR DIVERSE APPLICATIONS

Plant-based nanoparticle synthesis has emerged as a sustainable and promising alternative to conventional methods due to its simplicity, environmental friendliness, and improved biocompatibility. This article discusses the latest advancements in the green synthesis of various types of nanoparticles using plant extracts, with a focus on their applications in biomedical, environmental, and agricultural fields. Key phytochemicals such as flavonoids, alkaloids, terpenoids, and phenolics play a crucial role in the reduction and stabilization of nanoparticles. Silver nanoparticles (AgNPs) are the most synthesized type, known for their strong antimicrobial and anticancer activities. Inorganic nanoparticles exhibit high stability and potential in targeted therapy and pollutant degradation, while organic and carbon-based nanoparticles offer flexibility in drug delivery and diagnostic innovations. The use of plants such as Lawsonia inermis, Aloe vera, and Curcuma longa in nanoparticle synthesis has proven effective against pathogens and cancer cells with minimal toxicity. The integration of nanotechnology and phytochemistry opens new avenues in addressing global challenges in health, agriculture, and environmental conservation.
