Using modified hyaluronic acid and polyethylene glycol, researchers have created a bio-ink for 3D printing, which could be used as a scaffold to grow human tissues.

 .

Researchers have developed a ‘bio-ink’ for three-dimensionally (3D) printed materials that they say could one day serve as scaffolds for growing human tissues to repair or replace damaged ones in the body.

 .

From Rutgers University, US, the scientists explain that bioengineered tissues show promise in regenerative, precision and personalised medicine, as well as product development and basic research.

 .

Previous studies have shown that hyaluronic acid, which is a natural molecule found in many tissues throughout the body, has many properties ideal for creating customised scaffolds, but lacks the necessary durability for tissues. Instead, the Rutgers engineers used modified versions of hyaluronic acid and polyethylene glycol to form a gel that was strengthened via chemical reactions and would serve as a scaffold. This 3D […]
