Abstract
Second near-infrared window fluorescence imaging (NIR-II FI) has attracted tremendous attention in bioimaging. Until now, most probes for NIR-II FI are nanomaterials that are metabolized via hepatobiliary metabolism. Such a metabolic pathway may take several months, causing long-term toxicity. Herein, we design and synthesize a renal-clearable PEGylated semiconducting oligomer (PSO) for the NIR-II FI of tumor. PSO is composed of a semiconducting oligomer (SO) backbone as an NIR-II fluorescence reporter and four poly(ethylene glycol) (PEG) side chains as water-soluble enhancers. PSO can emit an NIR-II fluorescence signal with the maximum emission at 1000 nm under the excitation of 808 nm light. PSO shows good biocompatibility and can be partially cleared out of body via renal clearance. PSO can be utilized for the NIR-II FI of tumor as it can effectively accumulate into tumor.
