Julian Sankey Capstone 2025

For our senior capstone, my partner Trent Rodgers and I set out to recreate Spider-Man’s web shooters through a chemical lens. Inspired by a shared passion for Marvel and material science, we began by researching polymer structures capable of mimicking the fictional webs. Our initial experiments used a sodium alginate-based solution–our “First Generation” formula–developed during a summer program at The Franklin Institute. This laid the foundation for more advanced experimentation. Our research deepened when we studied a promising paper by Fiorenzo Omenetto at Tufts University. His work became the basis of our “Second Generation” solution. We collaborated with Omenetto and mentors like chemical engineer Bill Rodebaugh and engineering teacher John Kamal. After securing $650 in funding from Braskem, we acquired key materials, including chitosan, dopamine, and silk fibroin. However, delays in chemical delivery and insufficient quantities hampered our ability to perform comprehensive testing. Despite setbacks, we successfully tested multiple chemical combinations to create a durable, web-like polymer. Our most promising experiment revealed a critical reaction window when the solution turned white and foamy, though limited resources prevented us from fully capitalizing on it. This project demanded persistence, collaboration, and creative problem-solving. I learned how to navigate scientific research, develop experimental procedures, and manage real-world project constraints. While our final prototype fell short of full functionality, we took significant steps toward translating fiction into reality. With more time, materials, and focus, I believe this project could have achieved its ambitious goal. Below is a link to a drive of uncut lab recordings we took over the year.
