    Surface Emitters in Organic Solvents

## Description

- description: Electrochemical techniques conventionally lack spatial resolution and
    average local information over an entire electrode. While advancements in spatial
    resolution have been made through scanning probe methods, monitoring dynamics
    over large areas is still challenging, and it would be beneficial to be able to
    decouple the probe from the electrode itself. In this work, we leverage single
    molecule microscopy to spatiotemporally monitor analyte surface concentrations
    over a wide area using unmodified hexagonal boron nitride (hBN) in organic solvents.
    Through a sensing scheme based on redox-active species interactions with fluorescent
    emitters at the surface of hBN, we observe a linear decrease in the number of
    emitters under positive voltages applied to a nearby electrode. We find consistent
    trends in electrode reaction kinetics vs overpotentials between potentiostat-reported
    currents and optically-read emitter dynamics, showing Tafel slopes greater than
    290 mV decade-1 . Finally, we draw on the capabilities of spectral single molecule
    localization microscopy (SMLM) to monitor the fluorescent species identity, enabling
    multiplexed readout. Overall, we show dynamic measurements of analyte concentration
    gradients at a micrometer-length scale with nanometer-scale depth and precision.
    Considering the many scalable options for engineering fluorescent emitters with
    2D materials, our method holds promise for optically detecting a range of interacting
    species with unprecedented localization precision.
