The Implantable and Biodegradable PHBHHx 3D Scaffolds Loaded with Protein-Phospholipid Complex for Sustained Delivery of Proteins

Purpose PHBHHx (poly(3-hydroxybutyrate-co-3-hydroxyhexanoate)) is an excellent biomaterial for tissue repair. Here, we aim to develop a PHBHHx-based three-dimensional (3D) scaffold system for sustained delivery of proteins (insulin serves as a model protein).
