This technology addresses the limitations of traditional optical imaging probes (relying on intensity/wavelength changes), which are prone to interference, false positives, and inability to detect multiple targets. It uses luminescence lifetime as a stable parameter (unaffected by light source power or concentration) and prepares multifunctional polymer probes through advanced polymerization. Combined with time resolution technology, it accurately distinguishes and simultaneously detects multiple targets in spectral overlap and complex biological backgrounds.
