Regenerated wool keratin-polybutylene succinate nanofibrous mats for drug delivery and cells culture

Nevertheless, while showing good bioactivity and great drug carrier properties, keratin lacks of suitable mechanical characteristics. To overcome this drawback, keratin was blended with poly(butylene succinate) (PBS), a biodegradable and biocompatible polyester able to confer mechanical integrity to the keratin based materials.

Keratin (Ker) protein regenerated from readily available and low-cost wastes (e.g. raw wool, feathers and textile by-products) is a promising natural polymer for tissue engineering and drug delivery.
