碱性磷脂酶(ALP)是一种与许多癌症相关的水解酶,广泛分布于人体器官中,已被认为在许多医学和生物领域中都是重要的生物标志物。为了更好地检测ALP并对其成像,我们构建了一种新颖的比率式荧光探针APW,该探针可以快速(在不到15分钟的时间内)以高量子产率(Φ = 0.6)和高灵敏度(检测极限为0.46 UL -1)响应)到ALP。我们的研究具有重大意义,因为它使用了鲜有报道的新的比率响应方法,从而大大缩短了响应时间。此外,我们成功地将这种新型探针应用于细胞成像,并获得令人满意的结果。

We report a two-photon probe (FS1) which shows a 21-fold two-photon excited fluorescence enhancement in response to H2S and can selectively detect H2S in a rat hippocampal slice at a depth of 90–190 μm by using two-photon microscopy.
