文摘

A series of functional quantum dots (QDs) with widely tunable near-infrared fluorescence emission (620–750 nm) and lifetime (30–160 ns) were synthesized via lattice strain and showed excellent photo, colloid, pH, and lifetime stabilities. The well-defined targeting QDs were first developed for a living cell multilifetime encoding strategy to track and recognize specified tumor cell clusters dependent on lifetime distribution using fluorescence lifetime imaging microscopy.
