Rutgers biomedical engineers have developed a “bio-ink” for 3D printed materials that could serve as scaffolds for growing human tissues to repair or replace damaged ones in the body.
.
The study was published in the journal Biointerphases.

Bioengineered tissues show promise in regenerative, precision and personalized medicine; product development; and basic research, especially with the advent of 3D printing of biomaterials that could serve as scaffolds, or temporary structures to grow tissues. Hyaluronic acid, a natural molecule found in many tissues throughout the body, has many properties ideal for creating customized scaffolds, but lacks the durability required.
.
The Rutgers engineers use modified versions of hyaluronic acid and polyethylene glycol to form a gel that is strengthened via chemical reactions and would serve as a scaffold. “Instead of an ink color for an inkjet printer, we want the mixture to have properties that are right for specific cells to […]
