| Research Abstract |
Tubular membrane protein’s ion permeation function is available for biomedical applications such as cell stimulation devices. However, when considering that those proteins stimulate the multiple cells in parallel, it is not easy to evaluate each function to the cell at the same time by electrical measurements. Therefore, we propose the use of ion sensor to evaluate the protein’s electrical properties on the basis of its fluorescence images. In this study, we introduced target proteins into an artificial lipid bilayer membrane where the ion concentration gradient exists. Then, we observe fluorescence images and record electrical properties of the membrane.
