(PSs) are reported, which show excellent phototoxic indexes (PIs) up to 5800 against HeLa cells, which is, to the best of our knowledge, the highest value reported for any porphyrin so far. Furthermore, 67Zn isotope labelling allowed the determination of the ratio of zinc to platinum inside the cells using ICP-MS.
据报道,新型的基于四铂金属卟啉的光敏剂(PSs)对HeLa细胞显示出高达5800的优异光毒性指数(PI),据我们所知,这是迄今为止所有卟啉的最高值。此外,通过67 Zn同位素标记,可以使用ICP-MS测定电池内部锌与铂的比例。
