Laser-Activated Gel Forms Tissue Scaffolds for Medicine and Research

Facebook X LinkedIn Email
ZURICH, Nov. 5, 2024 — Using a laser and a light-reactive gel, a research team led by Hao Liu at ETH Zurich produced highly aligned microfilament structures for growing connective, nerve, and muscle tissue in a lab. The optically-based approach developed by the team could open new possibilities for building lifelike tissue models for biomedical research and translational medicine. To successfully fabricate tissues in the laboratory, researchers must replicate the way that the cells in biological tissues are aligned. In many cases, this is achieved by producing a 3D, biocompatible tissue scaffold with aligned...Read full article

    3d printing
    3D printing, also known as additive manufacturing (AM), is a manufacturing process that builds three-dimensional objects layer by layer from a digital model. This technology allows the creation of complex and customized structures that would be challenging or impossible with traditional manufacturing methods. The process typically involves the following key steps: Digital design: A three-dimensional digital model of the object is created using computer-aided design (CAD) software. This...
