**CDnir7** (Compound of Designation near infra red 7) is a macrophage selective probe with a long wavelength of near infrared (NIR) excitation and emission. With the deep tissue penetration optical property, **CDnir7** visualize the inflammation site in mouse paw (LPS injection model) using fluorescence molecular tomography. **CDnir7 **is also active probe for photoacoustic imaging and breast tumor in mouse model could be visualized by multi-spectral optoacoustic tomography (MSOT). **CDnir7** was also successfully applied for Alzheimer disease mouse brain imaging through MSOT.

Discovery of the NIR fluorescence probe **CDnir7** and in vivo imaging of inflammation. (a) Chemical structure of CDnir7. (b) Fluorescence images of mouse splenocytes and the macrophage cell line Raw 264.7. (c) Flow cytometry dot plot images of splenocytes and Raw 264.7. (d) CDnir7 detection in inflamed regions of live mouse paws using the IVIS spectrum. LPS (1 mg mL1 , 200 mL) was injected into the right paws 2 days prior to the imaging. CDnir7 (100 mM, 250 mL, 1% PEG and 0.1% Tween 20 in PBS) was injected via the tail vein and the image was obtained 30 minutes later. (e) Immunostaining images of CDnir7 and CD11b using the left rear foot (control region, e) and the right rear foot (f). Scale bar: 50 mm
