  • Coating gold surfaces with 11-Amino-1-undecanethiol self-assembled monolayer (SAM).
  • Culturing rat cortical neurons on electrode arrays with varying SAM pad sizes.

    • Main Results:

    • The terminal functional groups of the 11-amino-1-undecanethiol SAM are crucial for cell adhesion.
    • A 50 microm x 50 microm SAM pad size is optimal for immobilizing single cortical neurons.
    • Larger pads facilitate excellent neuron coverage on the electrode arrays.

    Conclusions:

    • This microfabrication technique enables precise control over neuronal cell culture and immobilization.
    • The findings support the development of advanced neural interfaces for research and medical applications.
    • Optimized surface chemistry and topography are key to successful neural-device integration.
