Abstract
This study explored the responses of cotton fabrics functionalized with lactateresponsive and non-re-sponsive polymers, focusing on color and pattern changes. Facial pattern samples were created using two monomer solutions and stained with anionic dyes. When immersed in 100 mM lactate, smiling faces gradually turned into crying faces. Pattern changes correlated with lactate concentration and response time, with full transformation observed after 120 min at 100 mM lactate. These findings suggest dye desorption from responsive areas enables visual, concentration-dependent lactate sensing.
