Optical probing of active membrane potential using lasers and microoptics.
We developed an optical probing system of active membrane potentials using lasers and microoptics. We measured the action potential of carp heart by multiple-wavelength and multiple-site optical probing system. Taking advantage of the coherent laser beam, an optical microprobing method for micro-study on ion channel activity is proposed.
