| Abstract | This experiment is to evaluate the biocompatibility of two polymer |
| materials, carboxymethylcellulose and poly(lactic acid) by measuring |
| bacterial growth on the polymer surface in a hyaluronic acid solution. |
| Polylactic acid (PLA) along with the carboxymethylcellulose (CMC) will |
| be divided into six separate pieces and submerged into a hyaluronic |
| acid solution to resemble more of a joint area. Then bacteria will be |
| added to the surface of the plastics. After a few days the bacteria will |
| be swabbed onto new petri dishes and the bacteria colonies will be |
| counted, thus determining which plastic is more biocompatible. The |
| hypothesis was that it is expected that both polymers will exhibit |
| adhesion and proliferation of S. epidermidis on their surfaces. However, |
| due to its already present use in medical technology PLA is expected |
| to grow more bacteria, so PLA will be more biocompatible than CMC, |
| and the hypothesis was supported. PLA grew bacteria in a uniformed |
| way, that also covered most of the petri dish. CMC did prove to be |
| biocompatible but it had a more of a separated growth pattern. CMC |
| also absorbed the hyaluronic acid solution which would not be practical |
| for the long-term goal. |
