Plasma Functionalized Scaffolds of Polyhydroxybutyrate Electrospun Fibers for Pancreatic Beta Cell Cultures

Fibrous scaffolds based on biodegradable and biocompatible polyhydroxybutyrate (PHB) were produced by electrospinning. The scaffolds were coated by a thin solid film of polypyrrole, PPyI, deposited by plasma polymerization technique. FTIR and Raman spectroscopy results confirm the presence of PPyI on the PHB fibers, in FTIR can be show the signal of the NH2 groups characteristic of the polypyrrole, so Raman show a broad band due to fluorescence...
