In tissue engineering, the ability to manipulate scaffold design characteristics is important to achieve functional tissue regeneration. In this study, degradable polar hydrophobic ionic polyurethane (D-PHI) porous scaffolds were synthesized using a lysine-based divinyl oligomer (DVO). Optimization...
