GelMA-Alg represents a breakthrough in bioink technology, skillfully blending the light-crosslinking capabilities of GelMA with the ionic crosslinking properties of alginate. This innovative composition results in scaffolds that are not only stronger but also more stable than those made with traditional bioinks. The GelMA component contributes remarkable biocompatibility, while alginate enhances printability, especially notable in its ability to be printed at room temperature. This makes GelMA-Alg particularly suitable for bioprinters lacking cooling printheads. Moreover, the alginate component can be utilized as a sacrificial material, depending on the specific requirements of the research design. This dual-functionality and adaptability of GelMA-Alg bioink make it an ideal choice for a wide range of bioprinting and tissue engineering applications, offering researchers flexibility and reliability in their experimental setups.
