Here we present a surface-micromachined Parylene neuro-cage array for the in vitro study of live neural networks. Various types of neuro-cages have been fabricated and several adhesion promotion techniques have been explored. The biocompatibility and mechanical robustness of Parylene neuro-cages have been demonstrated through cell culture experiments. Dissociated neuronal cell bodies have been inserted one to a cage and cultured, allowing neurites to grow out through Parylene channels and form live neural networks. In addition, there is no observable difference between neural growth on Parylene and on oxide surfaces. It is possible to use the same or slightly modified cage structures to accommodate different cells, leading to possible applications of this technology in cell study and drug discovery.
