Nanotechnology has emerged as a transformative platform in the management of chronic obstructive pulmonary disease (COPD), offering targeted, sustained, and patient-friendly therapeutic solutions. Engineered nanocarriers, including liposomes, solid lipid nanoparticles, dendrimers, nanoemulsions, and polymeric nanoparticles enable the precise delivery of bronchodilators, anti-inflammatory agents, gene therapies, and prodrugs directly to inflamed lung tissues. Surface modification with PEG or targeting ligands enhances mucus penetration, circulation time, and receptor-specific uptake while minimizing systemic exposure. Prodrug-loaded nanoparticles remain stable during inhalation and undergo site-specific activation in the diseased pulmonary environment, improving therapeutic efficacy and reducing off-target effects. Furthermore, regenerative medicine approaches, including nanoparticle-assisted stem cell delivery, have shown promise in promoting lung tissue repair and immunomodulation. In addition, an antioxidant nanoparticles, such as gold, cerium oxide, and zinc-based systems, effectively scavenge reactive oxygen species and reduce inflammation, addressing a key pathogenic mechanism in COPD. In vivo studies demonstrate improved lung function, reduced cytokine levels, and enhanced bioavailability using these nano-based strategies. Collectively, these advancements signify a paradigm shift in COPD treatment from broad symptom relief to precision-targeted molecular intervention. With further clinical translation, nanotechnology holds the potential to revolutionize disease management, restoring respiratory function and enhancing quality of life for millions of patients worldwide.
