| Summary: | Abstract The past two decades have witnessed breakthroughs in cellular‐scale bioelectronics and their widespread applications in life sciences, creating many powerful platforms for studying organisms directly and efficiently. These advanced devices can integrate seamlessly and intimately onto/into target cells and organoids, providing unprecedented functions and revolutionary capabilities. Bioelectronics with nanostructured designs are developed to allow for long‐term, stable monitoring of electrophysiological activities. This review summarizes nanostructured bioelectronics for cell electrophysiology recording, emphasizing the crucial roles of structural designs on functions and capabilities, e.g., intracellular access, high‐density multiplexed recording, multifunctional interfaces and the conformability to curvy biological shapes. Finally, the remaining challenges and opportunities in nanostructured bioelectronics are identified, and perspectives on the future developments toward their practical applications are provided.
