Durability of Medical Glue Compared to Natural Casein Glue

The objective of this experiment was to compare the durability of medical glue and natural casein glue. The significance of this project was to test whether natural casein glue could replace or be an alternate option for the medical glue used currently in hospitals and by doctors. To conduct this experiment, an incision was made in a small piece of pig skin. The glue was applied to the incision and left to dry over night in a refrigerator. A pulley system was used to stretch the skin to the breaking point and a force sensor was used to calculate the amount of force that it took to break the bond between the skin and the glue. A two sample t-test was used to compare the force that can be withheld by the casein and medical glue on incisions of varying depths. It was concluded that the medical glue could withstand the largest amount of force. The hypothesis stated that the 45 gram baking soda casein glue being applied to the shallow incision would withstand that greatest force. This hypothesis was rejected. The data collected from the experiment supports the research preformed currently. Since the casein glue withheld a significantly smaller amount of force than the medical glue, it can be inferred that casein glue should not be used for medical purposes.
