Living systems rely on the precise movement of ions through internal channels and pores to communicate critical information and to regulate their responses. Such ion migration-mediated signalling is ubiquitous in both animals and plants. However, ionic transport in plant tissues is less well explored, despite its crucial role in establishing signalling pathways. This talk explores electrokinetic phenomena in plant tissues, modulated by the circadian rhythm, and introduces biomimetic nanopore-based fluidic circuits that are capable of keeping a “memory” of previous ionic flow.

A biohybrid approach, integrating plant electrokinetics with nanofluidic memory architectures, can create a unified platform – offering untapped potential for sustainable communication and information processing technologies. The ultimate goal is to spark discussion and to identify a roadmap for merging plant biology, electrokinetics, and nanoscale engineering—with active collaboration from the Green-G community!
