离子敏感微电极(ion-sensitive microelectrode,ISME)又称离子选择性微电极(ion-selective microelectrode),它是从离子敏感大电极发展起来的测试生物细胞内液或外液的离子活度及其变化的一种生化参数探测电极。一般将其分为玻璃膜、固态膜和液态膜三种类型。早期主要以玻璃膜做为敏感材料,但由于制作上的困难,限制了它的应用。1971年,walker首用液态离子交换剂微电极(liquid ion-exchanger microelectrode)。这是此项技术的一个突破。此类电极具有制作方便、对细胞损伤小,易制成双管电
Ion-sensitive microelectrode (ISME), also known as ion-selective microelectrode (ion-selective microelectrode), which is developed from the ion-sensitive electrode to test the ionic activity of biological fluid inside or outside the cell and its Change of a biochemical parameter detection electrode. Generally divided into glass film, solid film and liquid film three types. Early mainly glass film as a sensitive material, but due to production difficulties, limiting its application. In 1971, walker first used liquid ion-exchanger microelectrode (liquid ion-exchanger microelectrode). This is a breakthrough in this technology. Such electrodes have the advantages of easy manufacture, small cell damage, easy to make double tube electricity
