Moringa oleifera-mediated silver nanoparticles for biomedical applications: a comprehensive review of plant part-dependent green synthesis, ultra-small AgNPs, and SWOT perspective
摘要
Moringa oleifera(MO) is a suitable plant source for the green synthesis of silver nanoparticles (AgNPs) due to its rich phytochemical composition.This review analyses recent studies on MO-mediated AgNPs synthesis, with an emphasis on the influence of different plant parts on nanoparticle formation and biomedical performance. In contrast to previous reviews, this work identifies cross-studies trends indicating that the choice of plant part and extraction method significantly determines the size, stability, and bioactivity of nanoparticles, including the formation of ultra-small AgNPs under selective extraction conditions. Key synthesis indicators and characterization techniques are briefly outlined. Biomedical applications of MO-derived AgNPs are discussed with a focus on their antibacterial, antifungal, anticancer, and wound-healing activities, with a brief SWOT overview. Overall, this review provides a concise and strategic perspective on MO-based AgNPs for size-controlled biomedical nanotechnology.
