用3，3‘-硫代二丙酸(TPA)单分子膜自组装修饰了金电极表面。PH敏感的TPA单分子膜被进一步衍生化以形成六氰基铁酸镍的单分子膜。该电极对钾离子和钠离子有分子识别作用，对钾离子在10~(-2)~1毫微米范围内的斜率为55 mV/C，表现出近能斯特响应。
A gold electrode surface has been modified with a monolayer of 3,3'-thiodipropionic acid (TPA) by self-assembly. The pH-sensitive TPA monolayer is further derivatized to form a monolayer of nickel hexacyanoferrate. This electrode shows molecular discrimination between potassium and sodium ions and exhibits a near-Nernstian response, with a slope of 55 mV/decade to potassium ions in the range from 10 -2 to 1 M.
