The long wavelength of **TiNIR** allowed the in vivo imaging of tumor in mouse model both is fluorescence and photoacoustic imaging. The affinity of TiNIR to target proteins were monitored by fluorescence and the bound protein was identified as heme oxygenase 2 (HMOX2). TIC maintain high level of reactive oxygen species (ROS) in the cell, and HMOX2 seem to detoxify cells by removing intracellular ROS.

Discovery of the NIR fluorescence probe for human lung TIC. (A) Fluorescence images show 32A, hLuEpi, TS10, and TS32 cells after being stained with TiNIR (100 nM) and DAPI (1 μg/mL) for 40 min, 37 °C. (B) Flow cytometry analyzed fluorescence intensity of 32A, hLuEpi, TS10, and TS32 cells after being stained with TiNIR (10 nM, 40 min, RT).
