Ce doped polyaniline nanoparticles for absorption and photoacoustic imaging response to GSH in vitro and in vivo

In situ synthesized nanozyme for photoacoustic-imaging-guided photothermal therapy and tumor hypoxia relief

“…Among those specific physiological signals in the tumor microenvironment (TME), glutathione (GSH), the most abundant endogenous active small molecular in cells and tissues, plays an important role in life activities and in maintaining the redox balance, while the concentration of GSH in cancer cells is 2–20 mM, three orders of magnitude higher than that in normal cells. 63 , 70 , 71 , 72 , 73 , 74 …”

Biomimetic semiconducting polymer dots for highly specific NIR-II fluorescence imaging of glioma

“…By contrast, increasing attention has been paid to the development of fluorescence imaging techniques for cancer theranostics in the second near-infrared window (NIR-II, 1000–1700) [ [7] , [8] , [9] ]. Since the biological tissues show less autofluorescence in NIR-II window than that in the visible (400–700 ​nm) or the first near-infrared window (NIR-I, 700–900) [ [10] , [11] , [12] , [13] ], NIR-II fluorescent probes can visualize the biological tissues with high temporal/spatial resolution and deep penetration [ [14] , [15] , [16] ]. However, most of the potential fluorescent probes do not exhibit a fluorescence signal in NIR-II window.…”
