One of the major challenges in treating emphysema is the regeneration of damaged lung tissue. Nanomaterials such as nanofibers and scaffolds can be used to create structures that mimic the extracellular matrix of lung tissue. These structures can support the growth and differentiation of stem cells, potentially leading to the regeneration of functional alveoli. Researchers are also exploring the use of graphene and other advanced nanomaterials to enhance the mechanical properties and bioactivity of these scaffolds.
