Application

甲基红溶液是一种 pH 指示剂染料，推荐用于检测各种样品中葡萄糖发酵的产酸细菌，如肠杆菌科细菌。

General description

<甲基红溶液是一种偶氮染料，当 pH 值低于 4.4 时会变成红色（黄色 pH 值 6.2，橙色 pH 值 4.4-6.2）。某些细菌可利用葡萄糖形成大量的酸，从而导致培养基pH值明显下降。其它物种不产生或只产生较少的游离酸。这种差异可通过甲基红观察到。 该测试用于区分肠道细菌。

Nanoporous and nonporous three-dimensional silicon nanowire arrays (SiNWAs) prepared with metal-assisted chemical etching method were investigated as photocatalysts in dye photodegradation systematically. In comparison with nonporous SiNWAs, nanoporous SiNWAs have higher surface area, larger pore volume, stronger light absorption and
