“…[29,[48][49][50][51][52] Distinguishable signatures from one WE have also been reached by reagentless systems. [53][54][55] Although valuable, the one-electrode multiplex methods are prone to two limitations, that is, i) the occurrence of crosstalk between the different tags and ii) the absence of spatial isolation, with the modification of the same WE with different bioreceptors. [26][27][28][29] To date, the crosstalk can be detrimental to the resolution of the current peaks over the voltammetric scan, therefore requiring a meticulous selection of the signaling tags to resolve the electrochemical signatures.…”

Multiplexing is a valuable strategy to boost throughput and improve clinical accuracy. Exploiting the vertical, meshed design of reproducible and low‐cost ultra‐dense electrochemical chips, the unprecedented single‐response multiplexing of typical label‐free biosensors is reported. Using a cheap, handheld one‐channel workstation and a single redox probe, i.e., ferro/ferricyanide, the recognition events taking place on two spatially resolved locations of the same working electrode can be tracked along a single voltammetry scan by collecting the electrochemical signatures of the probe in relation to different quasi‐reference electrodes, Au (0.0 V) and Ag/AgCl ink (+0.2 V). This spatial isolation prevents crosstalk between the redox tags and interferences over functionalization and binding steps, representing an advantage over the existing non‐spatially resolved single‐response multiplex strategies. As proof of concept, peptide‐tethered immunosensors are demonstrated to provide the duplex detection of COVID‐19 antibodies from distinct samples, thereby doubling the throughput while achieving 100% accuracy in serum samples. We envision the approach to enable broad applications in high‐throughput and multi‐analyte platforms, as it can be tailored to other biosensing devices and formats.This article is protected by copyright.

“…19,22 In particular, the manipulation of the spin polarization in wurtzite semiconductors is crucial for the development of hightemperature spintronic devices. 32 Despite their promising prospects as emerging topological systems, little work regarding the spin-polarized transport properties has been demonstrated for wurtzite QWs.Spin flip or spin precession in SOC systems is a crucial mechanism to drive spin polarization during electron movement, which has been used for spin field-effect transistors. 33 Based on SOC-induced spin flip, a bias voltage, breaking the…”
