“…The fundamental mechanism underlying learning and memory in biological systems is synaptic plasticity, which can be modulated by environmental chemical signals. , Previous research has employed memristors to mimic synaptic plasticity for brain-like computations. − However, the memristive devices are made of phase-change, metal-oxide, magnetic, or ferroelectric materials, in which the working mechanisms are different from the brain. In contrast, nanofluidic devices, which are in continuous development, − achieve many intelligent functions by controlling ion transport in nanochannels. − Specifically, a nanofluidic memristor is a device that can simulate synaptic behaviors depending on the ion transport in nanochannels, which is very similar to the ion-regulating mechanism in the brain. , Recent advancements in nanofluidic memristor technology have been achieved through various approaches, including the development of two-dimensional nanofluidic channels, , exploration of confined polyelectrolyte-ion interactions, , investigation into the elastic deformation of nanopores, utilization of angstrom-scale funnel-shaped channels, and implementation of multipore membranes …”
