Week 9: Final Testing (Weekly Meeting)

This week we finished our final testing for one of the hydrogels since the sample was tainted on the way to the lab. We first made the hydrogel by rinsing the mold in a calcium chloride bath. We then filled the mold with alginate infused with vitamin D and sealed the gel with another layer of calcium chloride. We then put the hydrogel in distilled water and left it for an hour to measure the release rate. We then transferred the hydrogel to a second container filled with distilled water. We repeated this process 3 times for a total of 3 samples. We then sent these samples to the lab to see if the release rate of the vitamin D changed every hour and compared the data to the other two hydrogel shapes we tested.
