Abstract

A composition including PPF or a PPF copolymer that can be used to fabricate biodegradable structures. The composition can be used in 3-D patterning (e.g., 3-D printing and sterolighography) methods. For example, 3-D patternable compositions include PPF or a PPF copolymer, a photoinitiator or photoinitiators, and a resolution control inhibitor or inhibitors. The compositions can be used to make biodegradable structures (such as cardivascular scaffolds). The biodegradable structures can be surface functionalized. The biodegradable structures can be used in methods of blood delivery in an individual.
