Post-treatments of polydopamine coatings influence cellular response.

Polydopamine (PDA) is the final oxidation product of dopamine or other catecholamines. Since the first reports of PDA coatings starting around 2007, these coatings have been widely studied as a versatile and inexpensive one-step coating option for biomaterial functionalization. The coating attach to a wide range of materials and can subsequently be modified with biomolecules or nanoparticles.

Electrospun PCL/PEO coaxial fibers for basic fibroblast growth factor delivery.

The poor innate healing capacity of fibroblastic tissues, such as pelvic floor fascia, is attributed to the scarcity of fibroblasts to produce collagen, as the main collagen producing cells. Coaxial electrospun PCL/PEO fibers containing basic fibroblast growth factor (FGF-2) were evaluated for the local and temporal delivery of FGF-2 for promoting fibroblast proliferation. PCL/PEO coaxial fibers with a highly porous surface were successfully developed using coaxial electrospinning.
