Modeling a 3-D Kidney Biomaterial

GOAL: PROTOTYPE A DEVICE TO PRODUCE A BIOMATERIAL WITH BULK ELASTIC MODULUS OF 1000 PA

• Photopolymerized material of Bulk elastic modulus of 1000 Pa

• Used a photo polymerization technique that allowed optically mediated cross-linking of biomaterials

•  How we illuminate the polymer, can determine properties of the biomaterial.

Conclusions:

LOCA Polymer went bad so had to use another that was not made for the specific UV-wavelength so it was at a much higher elastic modulus but still pliable. Repeated testing with the correct polymer would likely exhibit closer elastic modulus to calculations. The experiment did show the polymerization could be controlled with intensity, time of exposure, and distance placement of the LED.
