      The past few years have witnessed the extensive utilization of fluorophores with either near infrared (NIR) excitation or NIR emission for biomedical imaging because NIR light possesses much deeper tissue penetration than visible light. Lanthanide-doped nanomaterials are among the most prominent NIR contrast agents due to their abundant 4f-4f intra-configurational transitions. Up till now, many kinds of lanthanide-doped nanoparticles with NIR-to-NIR luminescence have been rationally designed, and their applications in bioimaging have been systematically investigated with encouraging achievements made. In this review, we summarize the most recent development of bioimaging based on NIR-to-NIR lanthanide-doped nanoparticles. The NIR-to-NIR luminescence mechanisms, the methods for enhancement of NIR-to-NIR luminescence, the instrumentation, the imaging modes and the challenges in NIR-to-NIR bioimaging are all discussed in this review.
