Being able to combine methacrylated gelatin and methacrylated hyaluronic acid is of key interest for scientists focused on tissue engineering and 3D bioprinting, as these two materials help generate an environment that more closely resembles an in vivo environment.

The following experiment was conducted to determine the viscoelastic behavior of variable mixtures of PhotoGel®-95% degree of methacrylation (methacrylated gelatin) and PhotoHA® (methacrylated hyaluronic acid) during photocrosslinking. 

The viscoelastic graphs of the 5% and 10% concentrations of methacrylated gelatin, combined with 1%, 2% or 3% methacrylated hyaluronic acid, can be seen below. Changes in concentration can lead to significant changes in hydrogel stiffness and other mechanical properties.
