Devices and methods comprising the microelectrode array for conducting cell

摘要

present invention, muscle cells (cardiomyocytes, skeletal muscle myocytes, and including, smooth muscle myocytes, but not limited to) the differentiation of conductive cells including a neural cell, maturation, and function of the analysis of It relates to a device and method including a micro-electrode array for. Microelectrodes present on the array, for stimulating cultured on substrates cells, and can be used for recording from the cells. In some embodiments, the substrate has a substantially smooth surface, and, in other embodiments, the substrate is, nano-textured (nanotextured), substantially nanometer wide-microns wide to provide a parallel grooves and ridges of the array.
