Electrospinning for polymeric implants in cardiovascular applications
Accelerated Degradation of Electrospun Poly(L-lactide) Scaffolds
Electrospinning is a method for producing fibrous polymer scaffolds that can be applied in drug delivery systems as well as for polymer-based implants. Biodegradable polymers for the purpose of cardiac tissue engineering are often applied as fibrous scaffolds for morphological mimikry of natural matrices but also drugeluting approaches are very promising. Hydrolytic degradation is one of the key parameters for successful application. The focus of our investigations is on monitoring accelerated in vitro degradation of electrospun nonwoven scaffolds. In the presented study degradation of poly(Llactide) is accelerated by alkaline hydrolysis. The process is characterized by weight loss, loss of molecular mass, surface morphology and thermal behavior of nonwoven samples, showing a fast degradation of the fibrous material within two weeks.
