	1	Microfabricated intracortical extracellular matrix-microelectrodes for improving neural interfaces显示文摘Intracortical neural microelectrodes,which can directly interface with local neural microcircuits with high spatial and temporal resolution,are critical for neuroscience research,emerging clinical applications,and brain computer interfaces(BCI).However,clinical applications of these devices remain limited mostly by their inability to mitigate inflammatory reactions and support dense neuronal survival at their interfaces.Herein we report the development of microelectrodes primarily composed of extracellular matrix(ECM)proteins,which act as a bio-compatible and an electrochemical interface between the microelectrodes and physiological solution.These ECM-microelectrodes are batch fabricated using a novel combination of micro-transfer-molding and excimer laser micromachining to exhibit final dimensions comparable to those of commercial silicon-based microelectrodes.These are further integrated with a removable insertion stent which aids in intracortical implantation.Results from electrochemical models and in vivo recordings from the rat’s cortex indicate that ECM encapsulations have no significant effect on the electrochemical impedance characteristics of ECM-microelectrodes at neurologically relevant frequencies.ECM-microelectrodes are found to support a dense layer of neuronal somata and neurites on the electrode surface with high neuronal viability and exhibited markedly diminished neuroinflammation and glial scarring in early chronic experiments in rats.
