Green Nanotechnology Sustainable Synthesis, Environmental Applications, and Future Perspectives

Green nanotechnology represents a paradigm shift toward environmentally sustainable approaches in nanomaterial synthesis, processing, and application. This comprehensive review examines the current state of green nanotechnology, focusing on eco friendly synthesis methods, environmental applications, and sustainability metrics. We analyze bio inspired synthesis routes, renewable energy applications, water treatment technologies, and environmental remediation strategies enabled by green nanomaterials. The paper discusses the integration of life cycle assessment LCA methodologies in nanotechnology development and addresses current challenges including scalability, cost effectiveness, and regulatory frameworks. Our findings indicate that green nanotechnology offers significant potential for addressing global environmental challenges while minimizing ecological footprint. Future research directions emphasize the need for standardized assessment protocols, improved synthesis efficiency, and comprehensive toxicological studies to ensure safe and sustainable nanotechnology deployment.
