Abstract
We report on the characterization and use of a Multispot Multiphoton Microscope, to investigate calcium dy- namics at intracellular level. We apply this technique to obtain a time resolution of a few milliseconds, even in full frame images at 512×512 pixels, in order to get the most information on the evolution and propagation of ionic calcium waves across adjacent cells in an intact cardiac tissue. Further we report on the progress of development of a Random Access microscope for very high speed all optical electrophysiological signal acquisition in cell networks. Our study opens the way to the investigation of arrhythmogenic disease in animal models at cellular level. © 2013 SPIE.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
