“…Yet, they rarely attracted much insight into the concomitant membrane process, e.g., adsorption and permeation, 9 no need to say the complication of the facilitated diffusion or the receptormediated nanofiltration, 10 all of which actually exert profound influences upon an ECL-engaging biofilm. 11 In light of this, fathoming out the key transmembrane dynamics in such a convergent context may help open up a new scope accessible to the conventional ECL modes, probably close to the way the nanopore and the electrofluorochromism worked in sequencing and neurophysiology. 12,13 Reviewing on the systems just exemplified, their spatiotemporal responsiveness to specific targets relied basically on routing cationic microcirculation by the electrode surface.…”

“…Besides, the extension of t P prolongs the depletion in I ECL , which readily set a criterion about the thickening of the diffusion layer. 11 Therefore, it made clear that the ECL illumination was not influenced by c[X − ] but by c[X − ]/dx in the Fickian diffusion. Exactly this tension motivated the membranotropic motion of anions in the electric field.…”

“…Down to the essence, it is the electric field that calls forth a membrane-traversing ionic gradient via redistribution of the inner Br − , otherwise the hydrophobic TOA would fence off external ions to swim inward. 11 This judicious claim acquired more supplements from Figure S7C−S7F that in all four haloids their I PL ZnPCs@TOA of HPTS got promoted by varying degrees (red column). As an in situ pH indicator, I PL 0 of HPTS decreases monotonically with the increase of acidity.…”

Recent upgrades in the electrochemiluminescence (ECL) technique showcased its brilliant knack in probing microscopic biointerfacial events, many of which were actually underlain by the ionotropic membrane processes, yet not being ostensive. Here, by modeling an artificial lipoid-supported porin ensemble, we explore and establish the ECL potency in profiling ion-channel activities. A lipophilic hollowed construct dubbed ZnPC was made out of the dynamic covalent chemistry, and its unique geometry was characterized that configured stoichiometric ECL-emissive units in a cubic stance; while the aliphatic vertices of ZnPC helped it safely snorkel and steadily irradiate in a biofilm fusion. After expounding basic ECL properties, the brightness was traced out in response to halogen contents that was lit up by F − /Cl − but down by Br − /I − . The overall pattern fitted the Langmuir isotherm, from which the membrane-binding strengths of the four were analyzed, compared, and collaterally examined in impedimetrics. On the other hand, one could derive anionic transmembrane kinetics from the time-dependent ECL statistics that pinpointed the ECL signaling via the nanocage-directed mass-transfer pathway. More data mining unveiled an ECL-featured Hofmeister series and the thermodynamic governing force behind all scenes. Finally, combining with halide-selective fluorometry, the synthetic conduit was identified as an ECL symporter. In short, this work develops a novel ECL model for the evaluation of life-mimicking membrane permeation. It might intrigue the outreach of ECL applications in the measurement of diverse surface-confined transient scenarios, e.g., in vitro gated ion or molecule trafficking, which used to be handled by nanopore and electrofluorochromic assays.

“…Second, it is considered that the experimental collision frequency is higher than the theoretical collision frequency due to the increase in the effective electrode area. In electrochemistry, the electrode area of a UME is usually observed under a microscope or is calculated from the steady‐state current in the CV using standard electrochemical technique 33 . The calculated areas from both the techniques naturally refer to the apparent area of the electrode.…”

This study introduces the electrochemical detection of a single microcystis on an Au ultramicroelectrode based on single-entity electrochemistry. The electrochemical collisions occur when the microcystis is adsorbed on the electrode surface. This hinders the oxidation of the electroactive redox species in the solution, thus making the current decrease like a staircase. In this experiment, the current decrease caused by the collision which requires an appropriate concentration of the redox species and initial potential, providing information on migration effect by zeta-potential, and collision frequency. Comparison of the simulation results of the finite element method and the experimental results suggested that the staircase current decrease caused by the microcystis can occur due to collision not only on the electrode surface but also on the surrounding regions of the electrode surface (i.e., the active area). These results suggest various applications of the single-entity cell detection using the electrochemical method for real-time analysis.
