ABSTRACT
With the lack of minimally invasive tools for probing neuronal systems across spatiotemporal scales, understanding the working mechanism of the nervous system and limited assessments available are imperative to prevent or treat neurological disorders. In particular, nanoengineered neural interfaces can provide a solution to this technological barrier. This review covers recent surface engineering approaches, including nanoscale surface coatings, and a range of topographies from the microscale to the nanoscale, primarily focusing on neural-interfaced biosystems. Specifically, the immobilization of bioactive molecules to fertilize the neural cell lineage, topographical engineering to induce mechanotransduction in neural cells, and enhanced cell-chip coupling using three-dimensional structured surfaces are highlighted. Advances in neural interface design will help us understand the nervous system, thereby achieving the effective treatments for neurological disorders. STATEMENT OF SIGNIFICANCE:
⢠This review focuses on designing bioactive neural interface with a nanoscale chemical modification and topographical engineering at multiscale perspective. ⢠Versatile nanoscale surface coatings and topographies for neural interface are summarized. ⢠Recent advances in bioactive materials applicable for neural cell culture, electrophysiological sensing, and neural implants are reviewed.Palavras-chave
