Abstract

Through rational design, block sequence controlled triblock copolypeptides comprising cysteine and tyrosine as well as a lysine or glutamic acid central block are devised. In these copolypeptides, each block contributes a specific property to the hydrogels to render them extrusion printable and antimicrobial. Three-dimensional (3D) printing of complex hydrogel structures with high shape retention is demonstrated. Moreover, composition dependent potent antimicrobial activity in contact-killing assays is elucidated.
