GelMA is a photosensitive biomaterial, it is used in combination with blue or ultraviolet light initiators to crosslink and cure under the action of blue light or ultraviolet light, the higher the concentration of GelMA, the greater the hardness after curing, it has good biocompatibility and can be mixed with cells for bio 3D printing.


GelMA hydrogels are very similar to the basic properties of natural extracellular matrices (ECM), which facilitate cell adhesion and proliferation. Moreover, its high moisture content, small molecules are easy to penetrate, which is beneficial to nutrient exchange, so it is suitable for encapsulating cells in three-dimensional culture.

Quality control test

Each batch of GelMA was confirmed by H NMR, HPLC and cytology, and its chemical structure, MA grafting rate was 50-60%, no cytotoxicity; GelMA formulated hydrogel, after adding blue initiator LAP, It can be cured quickly under the action of blue light.

1.Prepare 0.25~0.5% LAP solution, dissolve at 37℃;

2.Add GelMA, the final concentration is 5~10%, dissolve at 60℃, filter and sterilize with 0.22μm filter;

3.Mixed with cells, placed in the cartridge of the Blu-ray bio 3D printer;

4.3D printing, blue light (wavelength 405 nm) curing.

Attention:When the room temperature is below 25℃, the GelMA solution will solidify and need to be heated and melted before use.
