英文摘要	in this work, a novel and universal ion sensing platform was presented, which enables the visual detection of various ions with high sensitivity and selectivity. coaxial potential signals (millivolt-scale) of the sample from the self-referencing (sr) ion selective chip can be transferred into the ad620-based amplifier with an output of volt-scale potentials. the amplified voltage is high enough to drive a light emitting diode (led), which can be used as an amplifier and indicator to report the sample information. with this double amplification device (light emitting diode-based self-referencing-ion selective field-effect transistor, led-sr-isfet), a tiny change of the sample concentration can be observed with a distinguishable variation of led brightness by visual inspection. this led-based luminescent platform provided a facile, low-cost, and rapid sensing strategy without the need of additional expensive chemiluminescence reagent and instruments. moreover, the sr mode also endows this device excellent stability and reliability. with this innovative design, sensitive determination of k+, h+, and cl- by the naked eye was achieved. it should also be noticed that this sensing strategy can easily be extended to other ions (or molecules) by simply integrating the corresponding ion (or molecule) selective electrode.
