    摘要: A method for chemically acellularizing a biological tissue sample, such as a peripheral nerve, is provided. The method includes disrupting the cell membranes of the biological tissue sample, and then denaturing intracellular proteins within the cells of the tissue sample and removing the denatured proteins from the cells while preserving the extracellular matrix to produce an acellularized tissue construct.

    摘要: The present disclosure provides a regenerative peripheral nerve interface (RPNI) for a subject comprising an insulating substrate, at least one metallic electrode deposited onto the insulating substrate forming a thin-film array; a portion of the at least one metallic electrode surface having a layer of a first conductive polymer and a layer of decellularized small intestinal submucosa (SIS) coating a portion of the electrode, wherein a second conductive polymer is electrochemically polymerized through the SIS to form the regenerative peripheral nerve interface. The present disclosure also provides that a layer of muscle tissue contacts the regenerative peripheral nerve interface.
