| Abstract(in English) | One of the most popular optical mode for monitoring membrane potential is fluorescence.The purpose of this research is to develop a micro optical probe system for measuring membrane potential,in which fluorescent dye:NK2612 is used.We confirmed The beamwaist of incident laser light is 1.5μm,the absorption maximum is 767nm and the fluorescent maximum is 843 nm.Furthermore,we optimized the concentration of the fluorescent dye,confirmed fluorescence intensity is maximum when the concentration of the dye is 12.5μg, ml.We observed the dependence of fluorescence inten sity on the membrane potential and showed micro optical probe system is available for measuring membrane potential by fluorescence. |
