This project explores how photocatalytic nanoparticles and light can be leveraged to clean (i.e., remove stains and kill bacteria) textiles. This project is a collaboration between the Living Matter Lab, Unstable Design Lab and Accenture Labs, which stemmed from Fiona Bell's summer internship. Accenture Labs has continued to partially fund the project, which has been published in CHI'21 and received the Inspiration award at TEI'21. While a functal self-cleaning textile that can be applied to public spaces is the end goal, this work currently focuses on how "deStaining" and "Undyeing" can be used as intentional design tools that can selectively degrade the color of organic stains on textiles.
