Inflammation usually results in high‐level reactive oxygen species (ROS) and reactive
nitrogen species (RNS) not only in acidic tissue but also in alkaline tissue. However …

Despite the superior sensitivity of chemiluminescence over fluorescence, most
chemiluminescence reporters only emit visible light, and have low water solubility, making …

The second near‐infrared (NIR‐II) fluorescent imaging shows great potential for deep tissue
analysis at high resolution in living body owing to low background autofluorescence and …

Visualizing biomolecules such as enzymes in the deep tissue of living organisms via
molecular ratiometric fluorescent probes in the second near-infrared window (NIR-II) with a …

Reactive oxygen species (ROS) operate as signaling molecules under various physiological
conditions, and overproduction of ROS is involved in the pathogenesis of many diseases …

Reactive nitrogen species (RNS) as a class of vital reactive molecules, are essential for
maintaining homeostasis. Among RNS, nitric oxide (NO or NO.), peroxynitrite anion (ONOO …

Ulcerative colitis (UC), as the main inflammatory disease in the colon, is regarded as one of
the most refractory diseases by World Health Organization. Hydrogen peroxide (H 2 O 2) is a …

Small‐molecule‐based second near‐infrared (NIR‐II) activatable fluorescent probes can
potentially provide a high target‐to‐background ratio and deep tissue penetration. However …

Nitric oxide (NO) and glutathione (GSH) have interplaying roles in oxidant-antioxidant
balance. In this work, we developed the first example of a single fluorescent probe that …

Chemiluminescence imaging has been recognized as a valuable tool for ultrasensitive
detection of physio‐pathological events through elimination of background …
