。反斯托克斯荧光寿命成像……雷切尔·C·埃文斯等人证明了在活细胞中。在他们的研究文章(E202308602)中。这是通过设计基于有机-无机尿素载体中的三重态-三重态湮没上转换(TTA-UC)发色团的超小纳米粒子探针来实现的。染色细胞中UC寿命的波动表明，NPs可以用于绘制局部氧在亚细胞结构中的扩散图。
. Anti-Stokes fluorescence lifetime imaging…… in living cells was demonstrated by Rachel C. Evans et al. in their Research Article (e202308602). This was achieved through the design of ultra-small nanoparticle probes based on triplet–triplet annihilation upconversion (TTA-UC) chromophores encapsulated in an organic–inorganic ureasil host. Fluctuations of the UC lifetime in the stained cells suggest that the NPs can be used to map local oxygen diffusion across the subcellular structure.
