Abstract

Development of efficient fluorescent probes with intense far-red/near-infrared (FR/NIR) emission (> 650 nm) is of great importance in biosensing and bioimaging research. To date, a large variety of materials, including organic dyes, fluorescent proteins and inorganic quantum dots (QDs), has been extensively studied for the purpose of FR/NIR fluorescence imaging. Organic dyes and fluorescent proteins, however, suffer from limited molar absorptivity and low photobleaching thresholds, while inorganic QDs are highly cytotoxic in an oxidative environment: this has greatly limited the scope of their in vitro and in vivo applications. Exploration of novel FR/NIR fluorescent probes with a high biological compatibility, strong photobleaching resistance, and efficient light emission is highly desirable for biosensing and bioimaging. Herein, we designed and synthesized new FR/NIR fluorescent probes based on semiconducting polymers, fluorophores with aggregation-induced emission (AIE) characteristics or environment-sensitive fluorophores. We then explored the biomedical applications of these new fluorescent probes, which were demonstrated as very promising probes for in vitro and in vivo biosensing and bioimaging applications.
