3D BIOPRINTING

3D bioprinted living photosynthetic matter. Microalgae are growing efficiently in a structurally optimised hydrogel.

 

We are bioprinting photosynthetic living tissues with bio-optical properties inspired by cnidarians (corals and anemones).  3D bioprinting (also known as additive manufacturing) involves the creation of a 3D tissue design (stl file), usually created in a CAD (computer-aided design) environment. Bioprinting has revolutionised regenerative medicine via the rapid development of biocompatiple materials that address the need for artificial tissues and organs (e.g., Murphy & Atala 2014). 3D bioprinting is performed in the Chen laboratory at the Department of Nanoengineering at UCSD. The Chen lab is a leading research group in the field of 3D bioprinting and has been developing laser and UV light based 3D bioprinting techniques, including laser direct ablation, UV nanoimprinting, and stereolithography for biomaterials. A combination of different printing techniques are currently used  in the algal bioprinting optimisation process for biomicfuel (Lu and Chen 2004).
