D.; Wissinger, J. E. Polymeric medical sutures: An exploration of polymers and green chemistry. J. Chem. Educ. 2017, 94, 1761â€“1765. In Knutson, et. al. it was found that with new Kâ€“12 national science standards emerging, there is an increased need for experiments that integrate engineering into the context of society. Here we describe a chemistry experiment that combines science and engineering principles while introducing basic polymer and green chemistry concepts. Using medical sutures as a platform for investigating polymers, students explore the physical and mechanical properties of threads drawn from poly(Îµ-caprolactone) samples of different molecular masses and actual purchased absorbable and nonabsorbable medical sutures. An inquiry-based part of the experiment tasks students with designing their own experiment to probe the potential of melt blending poly(Îµ-caprolactone) with commercially available polylactide products in order to modify the properties of the â€œsuturesâ€ drawn. Through these lessons students gain an appreciation for the importance of plastics in our society and how scientists are working to develop more sustainable alternatives. Overall, this laboratory experiment provides a feasible, versatile, sophisticated laboratory experience that engages students in a relatable topic and meets many of the Next Generation Science Standards.
