Intravital confocal fluorescence lifetime imaging microscopy in the second near-infrared window
Optics Letters, 2020We present confocal fluorescence lifetime imaging microscopy in the second near-infrared (NIR-II) window to assess the morphological and biochemical information of live samples. A home-built superconducting single-photon detector (SSPD) was used to facilitate the NIR-II fluorescence lifetime measurement.

Multifunctional Photothermal Hydrogel in the Second Near-Infrared Window for Localized Tumor Therapy
ACS Applied Bio Materials, 2023A copper selenide-embedded gellan gum hydrogel (Cu2-xSe@GG) is designed as an "all-in-one" antitumor agent. The obtained nanocomposite hydrogel exhibits strong near-infrared light absorption and high photothermal conversion efficiency in both the NIR-I and NIR-II biowindows. The photothermal conversion efficiency achieves 58.8% under the irradiation of

Polymethine Molecular Platform for Ratiometric Fluorescent Probes in the Second near-Infrared Window
Journal of the American Chemical Society, 2022Visualizing 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 built-in self-calibration function can provide reliable information about relevant pathophysiological processes directly but so far is not feasible due to the lack of a ...

A phosphorescent probe for in vivo imaging in the second near-infrared window
Nature Biomedical Engineering, 2021In the second near-infrared spectral window (NIR-II; with wavelengths of 1,000-1,700 nm), in vivo fluorescence imaging can take advantage of reduced tissue autofluorescence and lower light absorption and scattering by tissue. Here, we report the development and in vivo application of a NIR-II phosphorescent probe that has lifetimes of hundreds of ...

Photothermal Fenton Nanocatalysts for Synergetic Cancer Therapy in the Second Near-Infrared Window
ACS Applied Materials & Interfaces, 2020Chemodynamic therapy (CDT) that utilizes endogenous hydrogen peroxide (H2O2) to produce reactive oxygen species (ROS) to kill cancer cells has shown a promising strategy for malignant tumor treatment. Nevertheless, limited H2O2 levels in the tumor microenvironment often compromise the therapeutic benefits of CDT, leading to cancer recurrence and ...
