一般說明
酚红是一种酚磺酞化合物。它在弱酸性水溶液中以磺化羟基醌的形式存在。在碱性溶液中，该染料形成亲水二价阴离子（一种小的红色阴离子，具有比黄色羟基醌更大的共轭体系）。
應用
在生物学和医学中酚红通常用作 pH 指示剂。 它也可加入微生物培养基中，用于鉴定大肠杆菌菌株。这一物质的临床诊断应用包括胃和十二指肠溃疡的检查以及眼科泪液功能的评估。酚红也可用作示踪剂，用于评估回肠粘膜的通透性，并评估牙科中细菌通过牙根填充材料的渗漏。
适合用作pH 指示剂。

Single-molecule localization microscopy is used to construct super-resolution images, but generally requires prior intense laser irradiation and in some cases additives, such as thiols, to induce on-off switching of fluorophores. These requirements limit the potential applications of this methodology. Here
