3D printed Bioactive Scaffolds for Tissue Repair and Drug Delivery
Document
Description
Combining 3D bio-printing and drug delivery are promising techniques tofabricate scaffolds with well controlled and patient-specific structures for tissue
engineering. In this study, silk derivatives of bioink were developed consisting of
silk fibroin and gelatin then 3D printed into scaffolds. The scaffolds would be
evaluated for small molecule release, cell growth, degradation, and morphology.
Preparations and design of the scaffolds are major parts of engineering and tissue
engineering. Scaffolds are designed to mimic extracellular matrix by providing
structural support as well as promoting cell attachment and proliferation with
minimum inflammation while degrading at a controlled rate. Scaffolds offers new
potentials in medicine by aiding in the preparation of personalized and controlled
release therapeutic systems.
