Enzymatically cross-linked peptide hydrogels for enhanced self-assembling capability and controlled drug release

Abstract

Self-assembled peptide hydrogels are a class of versatile materials with inherent biocompatibility and sound biological activities; however, they tend to exhibit weak mechanical properties and unsatisfactory release profiles of drug....

Novel luminescent hierarchical porous hydrogels with a three-dimensional interconnected network structure from feather keratin crosslinking reaction

“…Hydrogels derived from proteins/peptides show many advantageous attributes, for instance, viscosity, water holding capacity, and cohesiveness. 8 Protein gelation is the aggregation of denatured protein molecules, leading to the formation of a continuous 3D network. Generally, the network of the protein gel is constructed by non-covalent cross-linking ( e.g.…”

“…, disulfide). 8 Recently, many protein gels, including egg white, 9 soybean protein, 10 casein, 11 and keratins 12 have been reported. Thereof, keratins, a type of protein found in mammals (wool, hair, skin, horns, nails, and hooves), and birds ( e.g.…”
