Supramolecular systems have emerged as promising platforms for bioimaging and disease diagnostics driven by the growing demand for precision medicine and molecular diagnostics. Owing to their programmable molecular recognition, dynamic reversibility, and environmental responsiveness, these systems enable selective capture and signal amplification of disease-associated biomarkers in complex biological environments. Classical host-guest systems based on cyclodextrins, cucurbiturils, and pillararenes have been widely applied due to their well-defined and tunable cavities. In parallel, supramolecular systems constructed via covalent linkages or coordination-driven self-assembly serve as complementary strategies, offering enhanced structural stability, multifunctional integration, and controllable signal regulation. Collectively, these approaches expand the scope of supramolecular systems in precision diagnostics and bioimaging. This review summarizes recent advances in supramolecular strategies for disease-related biomarker recognition and highlights their potential in future diagnostic applications.
