Summary: Researchers have synthesized a highly bright near-infrared chemiluminophore through molecular engineering of the electron-withdrawing group. This chemiluminophore shows a 3 to 5-fold higher quantum yield compared to existing ones. By combining it with a cathepsin B-responsive moiety, an activatable chemiluminescence probe has been developed for real-time detection of deeply buried tumor tissues and accurate chemiluminescence-guided laparotomy in living mice.

Summary: In recent years, there has been great interest in the development of organic near-infrared (NIR) ratiometric fluorescent probes. Traditional intensity-based probes lack an internal standard method, resulting in unreliable and inaccurate detection signals as well as an inability to achieve quantitative determination of analytes. Smart dual emission probes with built-in correction ability have overcome the limitations of single channel fluorescent probes and enable reliable quantitative image analysis. Moreover, fluorescent chemosensors in the NIR window offer advantages such as high signal-to-noise ratio, low tissue damage, and deep tissue penetration. The combination of the advantages of ratiometric fluorescent probes and single-intensity-based NIR probes in NIR ratiometric fluorescent probes has led to their widespread application in biomedical research and clinical practice. This review provides a systematic summary of the recent advances (2020-2022) in this field, discussing the design strategies, sensing mechanisms, and bioapplications of these intelligent fluorescent probes. The challenges and prospects in this promising field are also addressed, with the anticipation that this work will inspire the development of organic NIR ratiometric fluorescent probes.

Summary: Optical nanosensors based on single-wall carbon nanotubes are able to capture the dynamics of biochemical processes. A one-step phase separation approach has been developed to isolate monochiral (6,4)-SWCNTs from mixed SWCNT samples, enabling high-resolution imaging in the near-infrared spectrum using standard Si-based cameras. (6,4)-SWCNTs modified with (GT)(10)-ssDNA become highly sensitive to the neurotransmitter dopamine, allowing for fast and high-resolution imaging of dopamine release from cells.

Summary: We report a dual-modal fluorescent and photoacoustic imaging probe for the detection of gingipain proteases secreted by P. gingivalis. The probe showed significant photoacoustic enhancement and fluorescence activation, with low detection limits. It demonstrated good diagnostic efficacy in porcine jaws and gingival crevicular fluid samples from periodontal disease subjects. Additionally, photoacoustic imaging of the probe was achieved in murine brains ex vivo.
