Green algae, a diverse and abundant bioresource, have emerged as a sustainable platform for 29 synthesizing nanoparticles (NPs) with wide-ranging applications. This review paper involves 30 the reduction of metal salts by biological factors such as algae, inducing nanoparticles with 31 unique properties, highlighting their eco-friendly synthesis, unique physicochemical 32 properties, and multifaceted applications in biomedicine, agriculture, environmental 33 remediation, and food technology. Algae-mediated NPs exhibit significant antimicrobial, 34 antioxidant, anticancer, and catalytic properties, making them valuable for drug delivery, 35 water purification, and biofuel production. From the 17 goals of SDGs, the role of algae is 36 emphasized, notably in potable water safe to drink (SDG 6), renewable and accessible energy 37 sources (SDG 7), hunger eradication (SDG 2), and climate mitigation (SDG 13). 38 2 Nanomaterials hold great promise across various applications, yet they face significant 1 challenges. Key issues include scalability for mass production, ensuring economic viability, 2 and navigating complex regulatory landscapes that can hinder their development and 3 implementation. Future research aims to optimize production methods, enhance 4 biocompatibility, and expand applications in nanotechnology. Green algae-based NPs 5 represent a promising, sustainable alternative to conventional nanomaterials, offering 6 innovative solutions for global environmental and health challenges.
