Abstract Point-of-care testing (POCT) requires rapid, quantitative results without the complexity of laboratory instrumentation. Conventional assays like ELISA and PCR are often limited by long processing times, multiple washing procedures, and a dependence on bulky, external power-consuming pumps.

1 Introduction Mechanically responsive optical devices, which can modulate their optical properties in response to mechanical stimuli, have garnered substantial attention for their potential applications in information encryption,[1-4] smart windows,[5-7] and sensing devices.[8-10] Generally, these devices in literature can be categorized into two types based on their optical transition, such as transparent-translucent/opaque[7, 11-13] and color change.[14-17] The...
