•Custom design housing of LED light in a 36 well plate using solid works.
•Polymer is injected into plate well and polymerized by shining LED light that emits and follows certain illumination profile
•Parameters to meet the 1000 Pa elastic modulus by;
•Intensity of the light
•Duration of the light exposure to polymer
•Distance between light and polymer
Circuit Design & Program
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.
Instron measurement of Elastic Modulus
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.
