Abstract
<p>In biochemistry, Ca2+ and K+ play essential roles to control signal transduction. Much interest has been focused on ion-imaging, which facilitates understanding of their ion flux dynamics. In this paper, we report a calcium and potassium multi-ion image sensor and its application to living cells (PC12). The multi-ion sensor had two selective plasticized poly(vinyl chloride) membranes containing ionophores. Each region on the sensor responded to only the corresponding ion. The multi-ion sensor has many advantages including not only label-free and real-time measurement but also simultaneous detection of Ca2+ and K+. Cultured PC12 cells treated with nerve growth factor were prepared, and a practical observation for the cells was conducted with the sensor. After the PC12 cells were stimulated by acetylcholine, only the extracellular Ca2+ concentration increased while there was no increase in the extracellular K+ concentration. Through the practical observation, we demonstrated that the sensor was helpful for analyzing the cell events with changing Ca2+ and/or K+ concentration.</p>
