Disulfide-crosslinked electrospun poly(gamma-glutamic acid) nonwovens as reduction-responsive scaffolds.

abstract：:Biopolymers are an attractive class of compounds for being used in biomedical applications as they are widely available from biomass. Their drawback is the lack of mechanical stability and the ability to tune this properly. Covalent chemical cross-linking is an often used approach but it limits usability due to legisl...
