Application

PhotoHA™-IRG bioink kit consists of methacrylated hyaluronic acid (HAMA) and Irgacure photoinitiator. Hyaluronic acid is the most abundant glycosaminoglycan in the body being an important component of several tissues throughout the body. While it is abundant in extracellular matrices, hyaluronic acid also contributes to tissue hydrodynamics, movement and proliferation of cells, and participates in a number of cell surface receptor interactions. The photoinitiator consists of Irgacure 2959 to be formulated in methanol (methanol not included), which allows UV crosslinking of the printed structure at 365 nm. PhotoHA™-IRG provides native-like 3D HA gels, and the final gel stiffness can be customized by changing HA concentrations and crosslinking.

In bone regenerative medicine there is a need for suitable bone substitutes. Hydrogels have excellent biocompatible and biodegradable characteristics, but their visco-elastic properties limit their applicability, especially with respect to 3D bioprinting. In this study, we modified the naturally occurring
