The Role of Ionic Liquids at the Biological Interfaces in Bioelectronics (Adv. Sci. 26/2026)

Ionic Liquids Biological systems rely on ion-based mechanisms, inspiring bioelectronic technologies that are based on interactions similar to biological interfaces. The neuron in the illustration represents ion-based signal transmission, while ionic liquids act as a bridge connecting this signaling with the electron-driven operation of electronic devices. In their Review (DOI: 10.1002/advs.202514481), Tae-il Kim and co-workers summarize mechanisms of ionic liquids and understanding the composition-structure-function relationships, which guide an important direction for next-generation bioelectronic technologies capable of interacting with diverse biological tissues.
