Polydiacetylene (PDA)-based colorimetric sensors have potential for rapid visual detection. However, their broader application remains limited by issues of sensitivity, selectivity, and stability. Here, the authors review functionalization strategies to overcome existing limitations, including chemical modification with reactive groups, conjugation with specific ligands or receptors, and integration with nanomaterials.
