摘要

Over population of invasive alien plant species (IAPS) disrupts the native ecosystems and poses a significant ecological threat. The extracts from various invasive plants contain naturally occurring compounds like phenolics and terpenoids, which act as reducing agents, transforming silver nitrate (AgNO3) into silver ions (Ag+). This biosynthesis approach helps in managing invasive plant populations and provides a sustainable method for producing silver nanoparticles (AgNPs). AgNPs have vital roles in enhancing human well-being due to the  diverse biological activities including antimicrobial, antioxidant, anti-inflammatory, anticancer and antidiabetic properties, offering effective solutions for a range of medical conditions. Traditionally, these nanoparticles are synthesized using toxic chemicals, raising concerns about environmental pollution and human health risks. While, the biosynthesis offers a promising alternative and eco-friendly method by utilizing natural resources, invasive and native plant extracts. Present strategy has the potential to revolutionize AgNPs production and contributes to a more rational future for both nanotechnology and invasive plant management. The current review explores recent advancements in the biosynthesis of AgNPs using various IAPS, characterization of AgNPs, challenges associated with AgNPs synthesis and  potential applications of AgNPs in the biomedical field. The detailed discussion on the unique characteristics of IAPS, their environmental impacts and effective control strategies has also reported. The major highlight of the study is to provide readers with a comprehensive and up-to-date summary on the diverse properties of AgNPs derived using  different invasive plant extracts, emphasizing the promising medical applications. Moreover, it examines the phytokinetics and toxicity of IAPS-based AgNPs, offering crucial insights into their safety and biological behavior.
