Abstract

A patch clamp microelectrode and a holder for coaxial photoactivation, which includes a glass tube, an electrode and a holder. The holder includes a mirror, an optical fiber interface and a catheter interface. The patch-clamp microelectrodes and holders that can be used for coaxial photoactivation use the method of partially filling the glass tube with high refractive index liquid to realize the liquid-core light guide, and transmit the external laser light to the cells that are in contact with the glass tube microelectrodes to complete the light. activation. The patch clamp microelectrode and holder that can be used for coaxial photoactivation can complete the photoactivation of cells and the recording of electrophysiological signals in situ. The invention has the advantages of simple structure, low cost and convenience, and is of great significance for neuroscience research.

Description

technical field [0001] The invention relates to a patch-clamp microelectrode and a holder that can be used for coaxial photoactivation, especially the method of partially filling the glass tube microelectrode with a high refractive index liquid to realize the liquid core light guide, and transmit the external laser light to the Cells are contacted with glass tube microelectrodes to achieve photoactivation. The patch-clamp microelectrode and holder that can be used for coaxial photoactivation can complete the photoactivation of cells and the recording of electrophysiological signals in situ. Background technique [0002] As an electrophysiological technique widely used in life science research, patch clamp technology provides an advanced research method for solving the transmembrane signal transduction of biological information. The working principle of the patch clamp technique is to use a glass microelectrode to seal the cell membrane with only 1-3 ion channels and an area...
