Nanomaterials in COPD: Emerging Therapeutic and Diagnostic Frontiers with a Focus on Metal-Organic Frameworks.

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality worldwide. Although conventional therapies are effective in controlling symptoms, they remain limited in altering the course of the disease and significantly reducing the chronic inflammation and oxidative stress underlying it. In this context, nanoparticles and nanomaterials are emerging as innovative tools capable of overcoming traditional pharmacological barriers due to their ability to deliver therapeutic oligonucleotides, antioxidants, and drugs in a targeted manner, modulate immune responses, and improve the bioavailability of active compounds.
