Abstract

Calcium ion is a very important messenger not only between cell and cell, but also in meridian main and collateral channels. A new neutral carrier PVC membrane based needle- type potential sensor was prepared, which shows a good selectivity for Ca²⁺. Response characteristics, pH, response time of sensor, other metal ions such as Mg²⁺, Na⁺, and K⁺ in measuring calcium ion were investigated. The resulting sensor has a liner range from 1.0 X 10^-6 to 9.1 X 10^-3 mol. L. The sensor will be used in the detection of Ca²⁺ in vivo in muscular tissues of the mice.
