| Abstract Scope |
Microelectrode arrays enable high-resolution recording of brain activity, essential for neuroscience and clinical applications. Rapid customization is valuable for adapting to specific research needs. The CMU Array, a 3D-printed microelectrode platform, offers reconfigurability but poses cytotoxicity risks if insulation is damaged due to the absence of biocompatible materials. To address this, we incorporated gold, a biocompatible material, into the CMU Array and fabricated gold nanoparticle-based arrays on flexible KaptonŽ substrates. These probes were tested in rat spinal cords, which present spatial challenges due to surrounding bone structures. The arrays successfully recorded neuronal signals in anesthetized rats during external limb stimulation. This work demonstrates the CMU Array’s adaptability in substrate choice, electrode design, electrical packaging, and material selection, highlighting its potential for safe and customizable neural interfacing. |
